I do not believe that you can change the device ordering, nor do you
really want to (imagine if you booted without your HBAs working for
example).  What you want to do, IMHO, is use e2label to write disk
labels on all your volumes and mount by that.

You can also use devlabel to get the disks appear to be in the order you
want, but you can't influence the order they're presented to the OS.  

I think what you really want is to be able to mount the right volume on
the right mount point and either approach will work for that.
