I apologise for the previous poor tip. I've just tested exactly this, i.e. a user-defined tool "run-mailcap %i" and it worked as expected. But then I realised what happened - updating the preferences after the save dialogue has already been opened does not update the preferences. So I can reproduce your problem. Therefore the workaround is to create the user-defined tool "run-mailcap %i", quit, restart, and then you should be able to use it as a post-save hook.
