Yes, that is in fact a bigger concern.  The artificial example I gave
is actually ruled out by the ICANN guidelines at the moment, I think:

   3. (a) In implementing the IDN standards, top-level domain
      registries will associate each label in a registered
      internationalized domain name, as it appears in their registry
      with a single script This restriction is intended to limit the
      set of permitted characters within a label.

The problem arises exactly as you say, when you have a name for
something (which is presumably a desired label) which cannot be
expressed in a single script.  My guess is that this state of affairs
is what the exception is there to deal with:

      Alternatively, a label may be associated with a set of
      languages, or with more than one designator under the conditions
      described below.

This is sort of a policy issue, though, and since I guess we're not in
the business of telling registries what policies they should adopt,
that's probably out of scope.

That seems like the best idea to me, yes.
