If you are looking for a list of browsers where you should utilize a non native sorting algorithm, my suggestion is don't.

Instead do a sort sanity check when the script loads and make your decision from that.

As the spec doesn't require a particular behavior in that regard, it is not immune to later change, even within the same browser line.

You could submit a patch to http://www.browserscope.org/ to include such tests in their suite. But again, feature detection is superior to browser detection.
