Search and sort videos/photos within a single URL?

I'd like to show all videos with a certain tag and have the list be sorted. Optimally, I'd like to sort it based on the least number of comments (would that be least popular or does that just track views?) Can anyone help?

Is there any way to do a search and sort within a single URL?

Like... http://network.ning.com/photo/photo/s...

Thanks
