Reddit like plug-in

I recently installed WP Frontend so that users can post on my blog RandPaulReview.com. Now I need a way for the articles with the top rated votes to show-up on the front of my blog page and hopefully the top of the category pages as well. Maybe a plugin that made high rated posts “sticky” for a limited period of time?

Plugins like Updownupdown, gd star rating, Vote it up, etc don’t seem to do quite what I want.

Thanks for the help! I’m racking my brain trying to find the answer to this one.
