Opinions/Ideas/Suggestions needed

I'm currently developing a script to clean out certain directories based on age and name. Part of the assignment is to ensure that the cleaning of a directory is done under the user id of the owner (script is running as root). I have a few ideas on how to do this, but I'd like to hear your opinions/ideas/suggestions on these (maybe I've missed something):
  • Move the relevant parts into a separate script which gets called by su
  • Built a separate script in memory and pass it to su <uid> -c 'bash -c' (probably going to end in quoting ****)
  • As above, but write to a temporary location
  • ?
Ideally, I'd like a mechanism like setuid/seteuid to make a temporary privilege deescalation for a certain block, saving me the hassle of passing parameters between those scripts.

Name
       uuclean - uucp spool directory clean-up

Syntax
       uuclean -p[pre] [ options ... ]

Description
       The  command  scans the spool directory for files with the specified prefix and deletes all those which are older than the specified number
       of hours.

       The -ppre argument causes the command to scan for files with pre as the file prefix.  You can specify up to 10 arguments.   A  without  any
       pre following causes all files older than the specified time to be deleted.  You must specify at least one argument.

Options
       -ntime	    Delete  all  files	whose age is more than time, in hours, (default is 72 hours) and that have the specified pre as their file
		    prefix.

       -m	    Send mail to the owner of the file when it is deleted.

       -ssystem     Delete files in all directories that are subdirectories of the per system spool directory that exists for system.  If  ALL	is
		    specified, then all system directories are processed.  ALL is the default.

       -ddirectory  Delete files that reside in the named directory.  The default directory is The option over rides the option.

       The  command typically starts the program.  In earlier versions, a deleted work file (C.file) would result in mail to the owner of the work
       file, regardless of the option.	Now, notification of deleted work files is sent to the user ID "uucp".	If the option  is  used,  mail	is
       also sent to the owner.

Examples
       Here are some example command lines:
       # uuclean -pLTMP. -pLOG. -n4 -d/usr/spool/uucp
       # uuclean -d/usr/spool/uucp/.XQTDIR -p -n
       # uuclean -smarkie -p -n84
       The third example deletes all files for the system that are older than 84 hours.

Files
       Directory with commands used by uuclean internally
