You will need multiple NPCs (ofcourse) for the flag etc.

First, you might need two stakes and if the guild (?) of the player is Red Team or Blue Team and he has the flag
(streqauls(#s(server.ctfowner),#a)){
his team get's a point.
You'll also need a sort of system npc, with
if (playerhurt){
and then the flag gets back at it's original place (?), setstring server.ctfowner,none.
then, the flag.
if the player touches the flag, setstring server.ctfowner,#a.
This hopefully helps you.
Oh and don't use this with your current CTF level ;P
