I've done this with arguments successfully, but when trying the following:

log = cpubound_$(Cluster)_$$([$(Process)+5]).log

These files get created:

The 1st 5 files all contain the "Job submitted from host" line only,
and the next 5 contain the rest of the expected output,
i.e. "Job executing on host", "Image size of job updated",
"Job terminated", etc.

I guess it's to do with when the submit file is parsed and at what stage
the substitution is done?

Yes, you're right. What you're seeing is the expected behavior. The $$ macros don't get evaluated until a job is matched. So when you do the submit, a log file with $$ unexpanded is created, which gets the submit event as you saw. Then, once the job is matched, the $$ is expanded, which creates the second log file that gets the subsequent events.

If you don't need the +5, this will work, of course:

  log = cpubound_$(Cluster)_$(Process).log
