Sort articles by most commented using disqus

I'm using disqus for my MODx blog commenting开发者_运维问答 system, but couldn't find anywhere a way to sort my articles based on the most commented one, or the most recent comments.

I see that there are already many questions similar to this so any help will be much appreciated us.

An article describing how to do it using Ditto/jot, it shouldn't be too difficult to modify it to work with disqus.
