The code had 2 mistakes:
1. amx_tmaxplayers wasn't registered right as the cvar (it was amx_tmaxplayer instead).
2. The calculation CT players was done correctly, but everyone else (also spectators) was considered as T in the calculation.
I 've added usage of get_pcvar_num instead get_cvar_num (it should effect a bit better performance) and I've changed the team change method by fakemeta (instead cs_set_user_team) with generating the right TeamInfo messages (that allows metamod bots to know they are in the new team and the human-player is also in the new team). So You don't need to skip bots in get_players function and balancing teams anymore.
Podbot mm V3B19m and higher versions are compatible with that method.
I haven't had time to test it. If someone could test it on some local PC and post here the feedback, it would be nice.
[EDIT]
Added fixes to bugs posted by users (leifont,cre8or,devil001).
