Numbering with letter

Hi,
I'm currently transfering my iPhoto library to a Finder photo management system.
I would really like to number my files with letters, when there is more than one with the exact same time
instead of the defaut behavior, where the first file is at the bottom.
I fould DrDrang post about his system, but it's managed outside Hazel. How could I reproduce this behavior in Hazel?
Thanks for any help
