I'm running out of suggestions over here.
Your exact command line yields this result:
zip warning: name not matched: in.txt
zip error: Nothing to do! (out.zip)
Well, it should, as I don't have an in.txt. Handing it an existing file, I get this:
zip -P pass out.zip result.txt
  adding: result.txt (deflated 7%)
.. and opening in the Finder correctly prompts me:
so there must be something wrong with your system.
Very Long Shot: What version do you get when you type this? (I can't imagine this is the actual problem, but you never know.)
zip --version
