Sort points with same X value

Hi all,

I find a discussion showing to sort point with X,Y,Z. and then I have a problem further to sort points with same X value and put into same branch, I don't know if there is a component to count how many points with same X value so I can put them in series component and generete branches. I try use the method shown on http://www.grasshopper3d.com/forum/topics/select-and-make-lists-with

and try to decomp. X value and put in branch but both unsuccessful.

hope someone can help.
