Is the concern with the apparent out-of-order numbering based on how
you want to access these devices in areas like fstab?  If so, I
suggest using glabel(8) to label the drives and then address them by
their labels elsewhere in the system.  I think there may be cases
where glabel won't be able to help, but it should work for many usage
scenarios.
