For easy reference I've added the values of 'outside-staff-priority
taken from scm/define-grobs.scm above.  The order you quote seems
correct based on these except for MultiMeasureRestText.  But in the
example you gave earlier you don't use a multimeasure rest text as
you attached \mark to the R1 rather than a markup.  (Did you think
the MM number was the MM text?)  When this is done correctly the MM
text appears in the correct position.

Two comments.  It seems as if the interleaving of the Score and
Staff objects now seems to honour the value of 
'outside-staff-priority
even without moving the engravers into the Staff context.  Maybe
Joe could shed some light on this.  The second comment is that the
value of 'outside-staff-priority for VoltaBracketSpanner as quoted
in the Learning Manual is wrong: it should be 600, not 100.  This
is the only error I can see.
