Yes if you order the names of the start-up scripts alphabetically.

However note that this probably doesn't do what you think you want it
to do: There is no general way to say "don't start domain Y until
domain X is up and running", because basically there is no good
definition for "up and running".  eg. Should it mean that the kernel
is up, or it's reached the login prompt, or all services on X are
listening ...?  You can't easily test for these conditions, so just
ordering the boots only has a minimal benefit.
