To get the order of files correct, I think you would be better off using the preprocess method of File::Find. Applying a sort on the contents of a subdir, before the call to \&Wanted. From the PODpreprocess The value should be a code reference. This code reference is used to preprocess the current directory. The name of currently processed directory is in $File::Find::dir. Your preprocessing function is called after readdir() but before the loop that calls the wanted() function. It is called with a list of strings (actually file/directory names) and is expected to return a list of strings. The code can be used to sort the file/directory names alphabetically, numerically, or to filter out directory entries based on their name alone. When follow or follow_fast are in effect, preprocess is a no-op.
Tuning the sort in PreProcess will allow you to work on files in the order that you want. I suspect you'd want to filter out '.' and '..' and any other undesirable directories so that Wanted is only working on ... the files you want! Code is untested. I can't believe it's not psellchecked
