I'm not setting it on my router locally but sending it over to Cogent as a community string per page 22 of their user guide. http://cogentco.com/files/docs/customer_service/guide/global_cogent_customer... They use it to manipulate how traffic gets back to me so that is incoming from my routers view. I also pad the AS for the networks that I prefer to come back through the other ISP..

Hi Vlade,
Well, if you are trying to balance the incoming traffic load with local-pref attribute, I can understand your disappointment :) Since it doesn't work at all this way: local-pref is local to an AS and deals with outgoing traffic only.
B) We have our own AS and IP space. I advertise them to both Cogent and our other ISP. I use the local preference attribute to share the load for incoming traffic between both ISPs. In the last 5 outages over the last few years, this has happened twice. I'm waiting on the RFO so I can further investigate why this happened. I think someone mentioned this in a post a few months ago too.
