Not 100% sure what your script does, but have you had a look at repoclose?

Usage: /usr/bin/repoclosure [-c <config file>] [-a <arch>] [-r <repoid>]
[-r <repoid2>]

  -h, --help            show this help message and exit
  -c CONFIG, --config=CONFIG
                        config file to use (defaults to /etc/yum.conf)
  -a ARCH, --arch=ARCH  check packages of the given archs, can be specified
                        multiple times (default: current arch)
  -b, --builddeps       check build dependencies only (needs source repos
  -r REPOID, --repoid=REPOID
                        specify repo ids to query, can be specified multiple
                        times (default is all enabled)
  -t, --tempcache       Use a temp dir for storing/accessing yum-cache
  -q, --quiet           quiet (no output to stderr)
  -n, --newest          check only the newest packages in the repos
