Here is how I calculate top 3 players in my 4738Z game mod:

Code 
rule("Calculate top players")
{
	event
	{
		Ongoing - Global;
	}

	conditions
	{
		Global.StartFlag == 3;
		Global.FinishFlag == False;
	}

	actions
	{
		Global.Top1 = First Of(Sorted Array(All Players(All Teams), Distance Between(Current Array Element, Global.BaseFinishLocation)));
		If(Entity Exists(Global.Top1) == False);
			Global.Top1 = Custom String("free slot");
			Global.Top2 = Custom String("free slot");
			Global.Top3 = Custom String("free slot");
		Else;
			Global.Top2 = First Of(Sorted Array(Remove From Array(All Players(All Teams), Global.Top1), Distance Between(Current Array Element,
				Global.BaseFinishLocation)));
			If(Entity Exists(Global.Top2) == False);
				Global.Top2 = Custom String("free slot");
				Global.Top3 = Custom String("free slot");
			Else;
				Global.Top3 = First Of(Sorted Array(Remove From Array(Remove From Array(All Players(All Teams), Global.Top1), Global.Top2),
					Distance Between(Current Array Element, Global.BaseFinishLocation)));
				If(Entity Exists(Global.Top3) == False);
					Global.Top3 = Custom String("free slot");
				End;
			End;
		End;
		Wait(1, Ignore Condition);
		If(Entity Exists(Global.Top1) == True && Global.LastTop1 != Global.Top1);
			Global.LastTop1 = Global.Top1;
			Big Message(All Players(All Teams), Custom String("{0} leads the race!", Global.LastTop1));
		End;
		Loop If Condition Is True;
	}
}
