It would seem reasonable to assume that on pages written in English
the test would be in English. You have to make some assumptions about
your users otherwise every site will have to offer pages in every
language.
Frankly I think that captcha's in general are a bad idea, they will be
broken in a few years anyway and be worthless. Even with visual and
audio, and, as I show, the audio ones are on occasion so bad as to be
almost unusable even by those with perfect hearing, your still left
with what to do about the deaf-blind.

Right, but how do you know what language the viewer is using? Just
because your page is in English doesn't mean I'm a native English
user. In other words, a language-specific validation methods is
going to add more cognitive load with no additional security
benefit. An ideal solution should be language-agnostic, which is
what the current audio and image captcha does.
It's a tough nut to crack. We want something only a human can solve
which doesn't presume a certain language proficiency and is
accessible. Non-trivial at best.

One other tidbit. The numeric puzzle solving example you give
would have a lot of internationalization issues. You would need
localized translations of every question, which is probably not
going to happen. The web is not just in English.
