Align to the edge of an object

Im working on a system that loads text from an external source and scrolls the information across the screen. I’ve figured that part out but what I need to know how to do is get the loaded elements(which are textboxes in movie clips) to align to the right of each other respectively when loaded since they all will have different widths based on how much text is in there.

Example:

[Loaded movie clip with text here number 1][Loaded movie clip with text here number 2][Loaded movie clip with text here number 3]

I hope that makes sense, thanks in advanced.
