Sorting car Park places along project outer boundary curve

Hello folks , im trying to sort park places along the project outer boudnary curve , as you can see in the image i have the outer boundary curve of the project and those points are the element point location of the park places , whats the best way to do this? i tried closest point to node and use paramtr at point but still didnt sort them perfectly?

You want to number them?

If so. I use a Spline to do that.

thank you i figured it out !
