Yes, this is correct.
Please forget restart scoreboard and msgbserv.

I recommended to create different group name for comp128-comp131.

If you want to run scored on this 4 hosts,
you need to specify the hosts to run scout or scored.
If group name is not created, you must run:
    # scout -g comp128+comp129+comp130+compcomp131
    # scored
or
    # sc_watcfh -g comp128+comp129+comp130+compcomp131 ...

If you create group for comp128-comp131 (for example develop), you can run:
    # scout -g develop
    # scored
or
    # sc_watcfh -g develop ...

if you plan to add second cluster hosts, you may run separate msgbserv.
You can run multiple msgbserv one one hosts (with different port number),
then you want to add hosts in develop cluster, you must restart scoreboard
and msgbserv for development cluster.
You don't need to restart msgbserv for main cluster in this case.
