FYI I fixed this issue upstream now:

commit 41d0f8fdf1905612ef389cb7b58c5377394f855b (HEAD -> master, 
origin/master, origin/HEAD)

     installer: Order install CDROM before any manual CDROMs

So you should be able to drop the bootorder bits, it should work 
correctly using --cdrom $windowsmedia --disk $virtiowin,device=cdrom ...
