There's no system built-in to MediaWiki for detecting Tor nodes (they are not open HTTP proxies, so a search for them would not work even if the old proxy-blocking code still works, which I don't know if it does).
You'd have to rig up a system for detecting Tor nodes, and/or use a list of open Tor nodes.
This said, an extension for this has long been on my to-do list. I might look into it at some stage.
