It looks as though the GitHub Issue feature is broken, at least for some that I've seen lately; looks like the page templates have changed.
I have a fix that works for me at jantman/userscripts@a336679#diff-73bd547090c7663e2f68bb82ad747579
The project might also be of interest to you. It makes heavy use of the card naming logic from Trello-Bookmarklet, but wraps it instead in a GreaseMonkey script that displays a context menu allowing you to select any list on any board.
