Unfortunately, BBFILE_PRIORITY only affects the choice of what *recipes* to use between the different layers, not config files or classes. The latter are found via BBPATH, which is incrementally appended to by each layer.conf. This separation is unfortunate, as it means part of the layer priority is in the user's hands (or the script generating bblayers.conf, if using one), and part is in the layers' hands (layer.conf), but that's the way it is for now.
