I don't quite understand your screenshot according to your text.  
The screenshot shows us a lot of m4b files with tracknumbers that have no leading zero and 1 file that has a leading zero. The filenames just look the other way.  
So could it be that you are want to change the filename to leading zeros and not the tracknumber?

Anyway:
