Re: ATT - Qwest ... Localpref issue?
Graham, We have the same issue as you, although it has been that way since the beginning. Our primary is Level 3, and backup CenturyLink. We have been forced to only announce certain prefixes out each in order to get a balance. CenturyLink has told me that they do not support communities. Unfortunately I have much longer on my contract than you. We are even having problems routing to AOL Yahoo on CenturyLink. I've had to refuse those routes from CenturyLink since Yahoo prepends out Level 3.

Re: ATT - Qwest ... Localpref issue?
I don't like it as it's a slower to converge solution, but look into BGP conditional advertising. Or better yet, tell AM you want to move to the Qwest internet product. You want to peer with AS 209.

Re: ATT - Qwest ... Localpref issue?
This is one of the reasons that I thought a useful output from the opsec or idr working group would be a documented set of community functions. Not mapped to values mind you. but I really like to say to providers do you support rfc blah communities or what's your rfc blah community mapping rather than what communities do you support.

Qwest uses 80 for peers; 100 for customers. As I'm sure Qwest had ATT as a peer prior to today (and you tagged as a customer), it probably should have been 80 since the beginning.
