Just a brainstorm:

There is a lot more conditions and commands that could lead to a new map, you could add those (take a look at mapchooser for other events that can cause mapchange including special cases like bonus round/time) then you could also try to hook on commands that cause change (like nextmap).

By looking at the code slightly I can't see a test if the round is the last (winlimit or round limit).

for clarification, what is the purpose of "sm_nextmapinfo_loop" ?
