Car Positioning System

Hello,

I am currently developing a car racing game and here I define the positions by this script. But as soon as two or more cars are in the same position, I realized that the system is not working correctly and I get the distances of the cars to the waypoints. But I cannot order now correctly. What I want to do is, if two or more cars are in the same position in the race, I want to get "distances[]" and "carPos[]" values and read them and compare them to find the correct positions of the cars in the race. By the way, I am sorry this topic may be asked tens of times but I really couldn't find a nice solution.
