This is really a bug in MacOS X!

Setting aside my earlier flippancy, Apple _seems_ to be deprecating file
types in deference to file name extensions. Which isn't to say that file
types won't be supported indefinitely, but you should count on less and
less files being tagged with appropriate metadata by their creating
applications, because so far Apple has not gone out of their way to ask
developers to tag these files, nor have they presented a viable
alternative which maintains the functionality of HFS type codes.  But this
is a rant which is off topic for this list.  Your suggestion sounds fine.
