I think these lines only apply when the tuplet bracket is present.
When the triplet is beamed, as here, there is no bracket.  That's
why I suggested overriding TupletNumber.

Tuplet brackets and numbers are normally within-staff objects.
There certainly are problems when they are included in the
outside-staff objects by giving them an outside-staff-priority,
as other properties such as 'direction then need to be specified
as well.  There may be more: tuplet brackets/numbers were not
designed to work as outside-staff objects.

The basic problem you have seems to be the collision of
tuplet brackets/numbers with Script objects:

\relative c'' {
 \times 2/3 {
   \stemUp
   bes8^\trill
   r
   bes^\trill
 }
}

If this were fixed you wouldn't need to mess with outside-staff
objects, would you?
