A dreaded top post... eeegad!
Sorry to point you to such a long piece just to have you find out
you're SOL in Panther. And even in Tiger you may not be any better
off if the application in question doesn't assign a TYPE and CREATOR
code of old Mac OS variety when it saves a new doc. UTIs may take a
bit of time to get used to, but you'd have better luck guessing one
you didn't know than with the old kind of type codes. The four char
code length saw some applications with really odd codes that weren't
easy to make a mental mnemonic association for.

After developing a small case of information overload reading that
article, which was very interesting, I'm left with the understanding
that while Tiger supports a new and impressive means of file typing,
Panther doesn't have any of that. I'm assuming that I'm basically
S.O.L. on limiting "choose file" to strictly PDF files as that
command relies on files to have creator and file type codes which OS
X has gotten away from using. As much as I like OS X, I really wish
that both ends of the horse would work together. Kind of stupid for
Applescript to rely on something that the OS is getting away from...

choose file of type {"PDF "}
http://lists.apple.com/archives/applescript-users/2005/May/msg00094.html
offers some explanation, but does Panther support type
identifiers. I don't think so as I don't set a "type identifier"
listed in the "info for" properties.
There's more than one strategy for type identification. The
"official" one supported in OS X is still file name extensions. But
it does support the old Mac OS type and creator codes too, though
it doesn't require them. The metadata also supports MIME types as
identifiers too. The new UTI that Bill Cheeseman was talking about
in the archived message you linked to above is a system of typing
that solves a host of typing issues, and can still make use of the
other typing mechanisms through cross-referencing of types to a UTI
type. If you want to get a better picture of this you might click
