Bulb Malfunction relay replaced, now running lights and radio not working

I took my car into the shop for some work before its VA emissions and safety inspections. The brake lights weren't working, so the shop replaced the bulb malfunction relay (in addition to re-doing the exhaust and trying to figure out why the car won't shift into Park). Once I had paid and picked the car up I noticed that three of the rear running lights (both driver's side, bottom passenger's side) weren't working, and the radio doesn't seem to be receiving power. Could some wiring have been disturbed while they were looking for the problem with the gear shift, or replacing the bulb malfunction relay? Or do I just have exceptionally bad car luck this week?
