[RESOLVED] Sorting an array after referenced movieClip x postition

I have an array containing several references to movieClips.
I want to sort that array depending on the x position to the clips.

What I'm wondering if anyone has solved this problem before and what the best solution might be.
Perhaps the best way is to include the x-positions in the array; like an 2d array, then sort that array?

Using an 2d array worked, but found another better solution.
