Sorting nodes based on votes and age

Hello,
It could be very basic question but I couldn't figure out how to do that.
I have bunch of nodes that has some kind of voting capability. I want to build a frontpage that sorted by following criteria. I want to calculate some kind of weight which is function of vote count and age of node. For example 2 days-old node with vote count 10 should has higher weight than 3 days-old node with vode count 10. You can read about detailed algorithm from this link. http://code.google.com/intl/tr-TR/appengine/articles/overheard.html

Is there any module with this functionality? Also views module integration could be very useful.
