This post describes Google Trends PHP API for Hourly Updates: http://blog.teamgrowth.net/index.php/search-engine-optimization/google-trends-php-api-for-hourly-updates

You fetch the ranking hourly and then you calculate the avarage rank and order by that. this is more the around-the-corner-thought-answer to your question, I know, but some thuinking has to be left to you and what's the (technichal) problem, anyway?
