Take three text_scripts, all with outside_staff_priority of 450,
and with
script_priorities of 201, 202, 203.

Convert them to three text_scripts with outside_staff_priorities
of 450,
451, 452, so that the script_priority is moved to outside_staff

What would happen if there was a TextScript at the same
moment with an 'outside-staff-priority of 451, set by
the user?

The only way to have a TextScript at the same moment with an
'outside-staff-priority of 451 is to use \tweak for the particular
'outside-staff-priority, e.g.

c4^"1"^"2"\tweak #'outside-staff-priority #451 ^"3"

No, if you have multiple voices in one staff the 'outside-staff-priorities can be \overridden independently at the same time in the several voices.

A look at your table in the learning manual shows that the different outside-staff-priority values vary by 50. So if we had 51 TextScripts, then
the outside-staff-priority would have an issue.  But if we had 51
TextScripts, then I'm fairly certain that there would be lots of issues.

Indeed.  But at least there is plenty of headroom with a gap of 50.

But in the interest of the simplest code that provides the desired
functionality, I've changed the code to have the outside-staff-priorities in
the above example be 450, 450.1, 450.2.

I think this is much better.  I can easily imagine a user
changing the outside-staff-priority by one to change the
stacking order.  Changing it by 0.1 seems far less likely
to me.  It also makes it easier to document clearly, if we
think it necessary.

Of course, the question could now be phrased "What happens if a user set an
'outside-staff-priority of 450.2?"

Well, I sha'n't ask that ;)

Thanks, Trevor
