Actually I think it is a carryover from MetaCard to distinguish 16-bit
windows apps from 32-bit ones. Back "in the day", Win32 was used to describe
whether a piece of software was 32-bit compatible or not. However it
probably was a bad idea to make such a specific name. IMHO it should be by
platform ("Macintosh", "Windows", "SPARC", etc.) with optional abbreviations
("Mac", "Win", etc.). To test for whether it's OS X or not, should be a
simple systemVersion check (which would mean that the systemVersion function
should be tweaked accordingly, like:

if the platform is "Mac" then
  if the systemVersion >= 10 then
    -- do OS X stuff
    -- do OS 9 stuff
  end if
end if

That's my 2 cents...
