This script applies in discussions list on scripts (yours and of others).
It adds 3 element sets:
The author's list in the hoverable dropdown menu is sorted based on the usernames as they appear on the page.
It's partially based on this script: userscripts.org Bullshit Filter (by kuehlschrank). Thanks a lot to kuehlschrank for making another great script.
It also works with [TS] Citrus GFork (thanks to decembre for contributing the needed changes).
Tested in Greasemonkey.
