It looks very nice. I found 3 bugs.
1st If you are as an admin+ball, scoring does not count(it doesnt say red team scored)
2nd If you are in red team, and do !blue it should say a message that you are in other team, or better change the !red and !blue to !team(it will auto find your team and say the message). If you are not in any team it will say You are not in any team. Also it says "IS_MTC - first byte must not be zero" when you do wrong team message.
3rd If a team win with maximum goals(2 by default) after /pit_all and the message that team won, you cant win again(only score, for example the score was 4-0 and nothing...)
