Yes Final Cut Pro 7 runs in OS X 10.9 Mavericks

Yes I upgraded to Mavericks and ran Final Cut Pro 7 last night, and yes it runs and plays back. Haven’t done extensive testing, but it does seem to work. And it has to have been on purpose as even After Effects CC had an update to make it work right in Mavericks, but Final Cut Pro 7 without an update still seems to work.
