There was a typo.. this should work.

autokill()
{
	xmin = -1300;
	xmax = 1935;
	ymin = -2502;
	ymax = 2530;
	zmin = -130;
	zmax = 999999;

	while(1)
	{
		wait 0.1;
		players = getentarray("player","classname");
		for(i = 0; i < players.size; i++)
		{
			if(players[i].sessionstate != "playing")
				continue;

			so0 = players[i].origin[0];
			so1 = players[i].origin[1];
			so2 = players[i].origin[2];

			if(so0 < xmin || so0 > xmax || so1 < ymin || so1 > ymax || so2 < zmin || so2 > zmax)
			{
				players[i] suicide();
				players[i] iprintlnbold("You are not allowed to go there.");
			}
		}
	}
}

ok dude i'll give it a whirl, fingers crossed im goin in!

Hope it works but in case it doesn't, didn't awe use some kind of way of stopping these exploits. Maybe give that a look and see how they did it.
