is there something like a <sort>-Tag in Mediawiki?
Sounds like a job for an extension. Sounds like a couple hours of work max if you know your way around PHP and Unix.
Look at wiki/extensions/Template.php. Wire in Unix sort(1) using PHP system('sort ...') and Bob's Your Uncle. Spend the rest of the time fretting about security issues.
If you're using Windows instead of some flavor of Unix, you have my deepest sympathy. Re-partition and install Linux and life will be simpler.
