When I 'telinit 4', I can see the script output in /var/log/messages:

When I 'telinit 3', there is no output from this script. It is like the script is not even being called.
Am I doing something stupid here? When I do 'telinit 3' from a higher runlevel, isn't it supposed to run all of the 'K*' scripts in rc3.d with a 'stop' argument?
Well, as I look at your links, I see none to start your script at runlevel 3, i.e. no S01myTest under rc3.d .... maybe I'm missing something ....
It's not supposed to start in runlevel 3. It's only supposed to run in levels 4 and 5.
The init process only runs K* under runlevel 4 (rc4.d) when exiting runlevel 4, then runs all of the S* stuff under the new runlevel. $0.02, no more, no less ....
That's not what the rc script appears to be doing. It simply checks the current runlevel and then runs all the scripts in that directory (kill scripts first, and then start scripts).
You originally asked why you were seeing no output from your test script when you did a 'telinit 3', I gave you a reason (links to activate the script not present in rc3.d) :-).
The links ARE there, but they are K* links, not S* links. I should see output showing the service shutting down when I go from 4 to 3.
My main point was that your description of the shutdown process does not seem to be accurate. Based on reading the 'rc' script, the runlevel switch happens first and then rc runs all scripts from the new runlevel directory.
If I switch from level 4 to level 3, the system will switch the runlevel to 3 and then run the kill scripts and startup scripts from the rc3.d directory.
The original problem has been solved. The script was not setting it's lock file properly, so it was being skipped when rc ran the kill scripts. Now that I've fixed that problem, I see the shutdown messages from the script as expected.
