Getting highest value

I have 3 movieclips and inside them loads external txt.files .
To MovieClip number one loads 1.txt, to number two loads 2.txt and to number three loads file 3.txt.

Allright everything works, but…
…what if I wantet to load the txt-file that has the highest number to the first movieclip example 65.txt, and to number two the 64.txt, and to movieclip 3 txt-file 63. And when there is txt-file called 66 in the folder it loads to movieclip one, and 65 loads to movieclip 2 etc… I think everybody gets the point.

Is it possible, that Flash look up the txt file that has the highest value?
