Mike I don't own that book, my Read shows examples (admittedly not that
extreme as these) where the bracket can be either/or up/down regardless
of stem direction.

Stone says " The numerals and the brackets should be placed at the
stem-side of respective groups so that the space at the note-heads will
be free for slurs and other articulations marks" then goes on to say "If
a group contains both upstems and downstems, it is often best to let the
majority of the stems determine the position of the numeral and the
bracket, but much depends on the amount of articulation. The less
interference with articulation and phrasing the better. ... Phrasing and
articulation marks are always placed closer to the note-heads than the
numerals and the brackets."

Also consider that the numeral is supposed to go under/over the note
head midway in the tupelet in terms of beat not in terms of middle by
distance. So this may also affect where the bracket lies if the extreme
notes are not the middle note.
