Magento 1.8.1 – Setup Resources Not Working

Personal I'm trying to create an installation script for magento module, but the problem is that he's not running my script and not save the core_resource table, anyone have any idea why that is?

I followed the following tutorial
Magento – Install, install upgrade, data and data upgrade scripts
