In case anyone is interested, I effectively created my own map_win event by piggy-backing off of the door_close event (requires left4dhooks):

PHP Code:

public void Event_DoorClose(Event event, char[] name, bool dontBroadcast)
{
    int client = GetClientOfUserId(GetEventInt(event, "userid"));
    bool bCPdoor = (GetEventBool(event, "checkpoint"));
    if (bCPdoor && L4D_IsInLastCheckpoint(client))
    {
        g_bMapWin = true;
        for (int i = 1; i <= MaxClients; i++)
        {
            if (IsClientInGame(i) && IsPlayerAlive(i) && GetClientTeam(i) == SURVIVOR_TEAM && !L4D_IsInLastCheckpoint(i))
            {
                g_bMapWin = false;
                break;
            }
        }
        if (g_bMapWin)
        {
            //stuff
        }
    }
} 


I am sure that can be refined but it resolves the issue for me.
