I second that this feature would be nice! dummy scores for fake players is the best way of making scoreboards for teams in vanilla Minecraft games at the moment. A way to test for those scores would make things a lot easier for game mechanics.
Searching around for this there seems to be a fair number of people wanting to do this with testfor, hopefully something like this gets integrated someday!
Whoops, didn't even realize I had it set to 32 chunks! Changed the options and that fixed the problem, thanks.
