Shipping Price in One Page Checkout – Order Review Returns Zero

Greeting, i created custom shipping method and it working good.
But, in one page checkout order review the shipping price is zero.
Here is the picture of that:

The shipping in the right sidebar is displaying correct value.
How to make shipping value in Order Review not zero?

Maybe global static code to only return shipping Order price (by passing tax calculation) since the requirement is outputting shipping price without tax.

Any help or lead is highly appreciated.
Thank you.

Additional Detail:

Magento version 1.7.0.2

Here are Tax Configuration:

• Tax Class Shipping = None
• Shipping price = Excluding tax
• Display shipping price = Excuding Tax
• Display shipping amount = Excluding tax
• Include Tax in Grand Total, Full Tax Summary, Zero Tax Subtotal = No

After tracing the code, function Mage_Tax_Block_Checkout_Shipping::getShippingExcludeTax() is responsible for zero price (tested by return constant value that not zero).

The shipping price in right side bar that returning right value is using Mage_Checkout_Block_Onepage_Progress::getShippingPriceExclTax() (tested by return constant value).

Here is the code of Mage_Tax_Block_Checkout_Shipping::getShippingExcludeTax()

class Mage_Tax_Block_Checkout_Shipping extends Mage_Checkout_Block_Total_Default
{
//... another code ...
    /**
     * Get shipping amount exclude tax
     *
     * @return float
     */
    public function getShippingExcludeTax()
    {
        //return zero
        //return 12345, front end shipping order review display 12345
        return $this->getTotal()->getAddress()->getShippingAmount();
    }
//... another code ...
}

Here is the code that not return zero shipment price

class Mage_Checkout_Block_Onepage_Progress extends Mage_Checkout_Block_Onepage_Abstract
{
//... another code ...
    public function getShippingPriceExclTax()
    {
        //return 12345, right sidebar display 12345
        return $this->formatPrice($this->getQuote()->getShippingAddress()->getShippingAmount());
    }
//... another code ...
}

Basically, my custom shipping is fetching price from table of city name and price field.
It use country_id, region_code, and city name from customer order to get price.

Here are the code of my custom shipping carrier

class Nirsoft_CityPrice_Model_Carrier extends Mage_Shipping_Model_Carrier_Abstract
                                               implements Mage_Shipping_Model_Carrier_Interface

    protected $_code = 'nirsoft_cityprice';
    private $destination_city;
    private $region;
    private $country;
    private $countryName;

    public function collectRates(Mage_Shipping_Model_Rate_Request $request)
    {
        $result = Mage::getModel('shipping/rate_result');
        /* @var $result Mage_Shipping_Model_Rate_Result */

        $this->destination_city = $request->getDestCity();
        $this->region = $request->getDestRegionId();
        $this->country = $request->getDestCountryId();
        $countryModel = Mage::getModel('directory/country')->loadByCode($this->country);
        $this->countryName = $countryModel->getName();

        $result->append($this->_calculateRate());
        if ($request->getFreeShipping()) {
            /**
             *  If the request has the free shipping flag,
             *  append a free shipping rate to the result.
             */
            $freeShippingRate = $this->_getFreeShippingRate();
            $result->append($freeShippingRate);
        }

        return $result;
    }

                  ->addFieldToFilter('name', array('eq' => ucwords($this->destination_city)));
