I don't quite understand this, you seem to be answering a different
question than the one Sylvain is asking.  If there aren't glyphs for
half-width digits, there are no glyphs to place or scale.  Fallback
will occur.

Keep in mind that "half-width digits" are normal ASCII digits, which
are typically included in all fonts that would be used for vertical
text display. So I think the problem is not one that exists in
practice.
