Funny Bug or feature?. instrumentNames rendered in reverse order than music

[Francisco Vila]

Hello.  This makes figures attached to notes to be printed in the
expected (ascending) order, but instrument names in reverse
(descending) order.  Another exciting case later below.

\version "2.13.34"

#(define sequence-number 0)
#(define-markup-command (score-sequence layout props) ()
 (set! sequence-number (+ sequence-number 1))
 (interpret-markup layout props
   (markup #:bold #:large (number->string sequence-number))))

\new Staff {
 \set Staff.instrumentName = \markup\score-sequence
 a'1^\markup\score-sequence
}

\new Staff {
 \set Staff.instrumentName = \markup\score-sequence
 b'1^\markup\score-sequence
}

\new Staff {
 \set Staff.instrumentName = \markup\score-sequence
 c''1^\markup\score-sequence
}

===========

When the staves are into a group in a single score, the behavior
reverses. Last note or note markup renders first, and last instrument
name renders last.

\version "2.13.34"

#(define sequence-number 0)
#(define-markup-command (score-sequence layout props) ()
 (set! sequence-number (+ sequence-number 1))
 (interpret-markup layout props
   (markup #:bold #:large (number->string sequence-number))))

<< \new Staff { \set Staff.instrumentName = \markup\score-sequence
        a'1^\markup\score-sequence }


\new Staff {
 \set Staff.instrumentName = \markup\score-sequence
        b'1^\markup\score-sequence }


\new Staff {
         \set Staff.instrumentName = \markup\score-sequence
        c''1^\markup\score-sequence }
