Is this possible?

Not if the script is more than 10 lines long.  Scripts run outside the IDE
cannot be edited if they're more than 10 lines.  What you're trying to do
above will need to be coded for within the script, which could be done with
a custom handler:

  on doMyRoutine
   lock screen
   doSomeStuff
   unLockTheScreen
   doSomeOtherStuff
  end doMyRoutine

  on unlockTheScreen
   if the platform = "macOS" then unlock screen
  end unlockTheScreen

FWIW, I don't believe "polling the OS" is a big deal.  But if you're really
concerned about it, you can store the platform info at startup in a global
or user property and reference this in your scripts.
