Input Actor format control question.

Ok. Now that I have the sprintf working with the textNumber function, how would I get an input actor's cursor to line up on the right? I've tried sscanf, but either I don't have the syntax correct or that isn't the correct function to use.
Problem:
How to place the cursor in a different position in the input actor's box:?:
TIA
