Create Adwords Script to automate pauzing Ads

We would like to have an Google Adwords Script that can pauze Ads for products that are temporarily out of stock. We use Magento and the idea is to use the Ad's destination URL and get the content of the HTTP response as a String, search the string for the text "out-of-stock" and if found pauze the Ad and send the e-mail the results. This should be a simple script to write for anyone experienced with javascript and Adwords Script. If you are not familiar with Adwords Scripts and Magento please do not bid.
