Hi Mike,

(setq org-export-latex-use-verb t)

appears to be the key here.  It is not documented as a variable, but  
when I set it to t in the *scratch* buffer and then run your test  
case, I get

This is normal text.

\verb~This is teletype text.~

\verb~This is verbatim text.~

which compiles just fine with LaTeX.

HTH,
Tom
