Thanks, Carl, I've added some notes, below.

I believe that the behavior is different depending on whether the bracket is
on the stem side or the note head side.  The notation references are
inconsistent about handling tuplet brackets on the stem side.

Granted, one sees it done in different ways. It would be desirable to be able to decide how to treat the tuplet brackets on the stem side. As Lilypond does it that way on the notehead side, it should be possible to do it on the stem side, without a manual adjustment in every case? 

Your example also shows a bug in the number location.  The number should be
centered on the center time value, rather than the geometric center,
according to Read.  So both 3's should be at the same horizontal location.

This is a point that I didn't mention; thanks for raising it.

Certainly, the numerals should align in the example under discussion.

Again, the placement of the numeral should be something which it is possible to choose. The following quote from Elaine Gould (p. 194) indicates that neither way is necessarily appropriate for the whole score:

" When one part of a beat is disproportionately long visually, traditionally the numeral remains at the visual centre of the group. However, where there are complex groups of tuplets, it is more helpful if the numeral moves to the rhythmic centre of the group, even if this is visually off-centre"
