How to increase point limit in deathmatch

I was wondering how to increase point limit on deathmatch for a gamemode. thanks

rule("Disable auto-completion")
{
	event
	{
		Ongoing - Global;
	}

	conditions
	{
		Is Game In Progress == True;
	}

	actions
	{
		Disable Built-In Game Mode Completion;
		Set Match Time(600);
	}
}

rule("Kills to win")
{
	event
	{
		Player Dealt Final Blow;
		All;
		All;
	}

	conditions
	{
		Number of Final Blows(Event Player) >= 100;
	}

	actions
	{
		Declare Player Victory(Event Player);
	}
}

rule("If timer runs out, declare winner")
{
	event
	{
		Ongoing - Global;
	}

	conditions
	{
		Match Time == 0;
	}

	actions
	{
		Enable Built-In Game Mode Completion;
	}
}

I added a few features, you can chose how long the game will be and how much time you want to play it.
