This looks like something I'd pull out a bit of DBI and DBD::CSV (don't let the name fool ya - you should be able to use tabs or spaces or whatever as separators, not just commas), and a small bit of SQL for. I'm sure you could do faster by hand, but I'm not sure it would be as bug-free, nor would it be nearly so quick to develop.
