Man is this an overdue lesson.
      I've been meaning to write this one for months now. It is rather fundamental, and important as well. This will allow your bots to "win games." That is, if he reaches the fraglimit set through the console then the Quake will exit to the intermission screen, just like regular servers.
      Lucky for us, this tutorial is butt-simple. In fact, it doesn't even require a new subroutine. All we have to do is call the player routine named CheckRules(), which is found in client.qc. This of course checks the player's frags and the time. Here, it looks like this:

/*
============
CheckRules

Exit deathmatch games upon conditions
============
*/
void() CheckRules =
{
	local	float		timelimit;
	local	float		fraglimit;

	if (gameover)	// someone else quit the game already
		return;

	timelimit = cvar("timelimit") * 60;
	fraglimit = cvar("fraglimit");

	if (timelimit && time >= timelimit)
	{
		NextLevel ();
		return;
	}
	
	if (fraglimit && self.frags >= fraglimit)
	{
		NextLevel ();
		return;
	}	
};

// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
void() bot_run =
// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
{

// his fighting thoughts. after a short while, he'll give up 
// on his enemy, but if he can see him, he'll always attack

	if (!(self.flags & FL_ONGROUND))
		return;

	check_for_water();

	if (visible(self.enemy))
		self.search_time = time + 6;

	CheckRules();
