I don't think ordering of results could be considered copyright, that's more like a method (since Bing presumably still crawls the sites and builds it's own index, with perhaps Google as a ranking factor). Real world consumer product companies copy what the competition is doing every day (it would be like US Airways putting it's interior designers on a Southwest plane), as long as Microsoft isn't using internal Google spies to steal code or something.
