Well the FAQ should at least answer the questions it asks, so either
the question needs to be updated, or the answer needs to be updated.
Right now, the question and answer don't match.

That would be handy, and useful, but atm I just need an exhaustive informal
answer wrt Unicode 6.0. :)

I'd drop the "using digital layout" part but otherwise, yes, that's a
good definition. If we had such a property it would need to state for
- what vertical directionality it has (if any). Horizontal scripts
would be none. Most vertical scripts would be top-to-bottom. Going
by Michael Everson's answer, Ogham would be bottom-to-top.
- If it has vertical directionality, how the text is transformed from
horizontal to vertical, i.e. are grapheme clusters rotated (laid
sideways wrt horizontal) or translated (kept upright like CJK).
