I do agree that negotiating while considering the entire scope can be useful and beneficial to both parties, but it can be counter-productive to disclose your priorities. If one of your priorities is not a priority for me, I can still pretend that it is a priority for me, and give-in after a lot of tough back-and-forth. Then I can use that as leverage as we go down the list. I feel that you should test the other side's priorities before you disclose yours. You would not want to trade an elephant for a pawn.
