sorting game objects when placing them in editor

is there a way to know the placing order of the objects in the script?

I'm doing a table style game and I need to know the next point to go represented by a game object, this is the one I'm trying to sort, in the scene I have many of them making a way from the first point to the last. I though to use the same name in all the objects and unity would do it himself, but the problem is that I have 3 types of these positioning objects which unity wouldn't accept them with the same name, so I can't use the name to order these objects by placing order...

Any help?
