Any link on the dm scepter, I couldn't find much on the net. I think the strange thing is that the was scepter relates to waset - Thebes, but in Thebes it was Amun and not Anubis or Set that were worshiped. Looking at the was again it looks like a line pointing to a steep upward direction. Also the circular fork on the bottom might refer to a circular origin - Earth coordinates? Who knows. I haven't read Bauval's book and I would expect that you would notice a relation of the top part of the was, with the 3 belt stars of Orion.
