Which office to go for? Should I go off waiting list?

[movingon]

Hey there
I had an interview a few weeks ago and got the "On this occasion we are unable to offer you the position you applied for as there were other higher scoring candidates. However, you did reach the standard required to pass the interview and your name has therefore been added to our waiting list for a period of 3 months from the date of this e-mail." e-mail!
Today there is an ad for one of my local delivery offices but it's the one I least want to work at (difficult to get to in rush hour).
The email said that if I apply for a position it stops me going for any others that might come up.
If I applied and got it, what are the chances I could switch to a different local office? They're all pretty much the same distance from where I live.
I just don't know what to do.
Any advice please?
