In case someone is interested: here comes the adapted snippet (with 
usage example).

\version "2.19.64"

\paper {
  #(define fonts
     (set-global-fonts
      #:roman "Vollkorn"
      #:factor (/ staff-height pt 20)))
}

globalFontFeatures =
#(define-music-function (feat) (list?)
   #{
     \applyContext
     #(lambda (context)
        (let loop ((x all-grob-descriptions))
          (if (not (null? x))
              (let ((grob-name (caar x)))
                (ly:context-pushpop-property context grob-name 
'font-features feat)
                (loop (cdr x))))))
   #})

\layout {
  \context {
    \Score
    \globalFontFeatures #'("ss11" "dlig" "liga=0")
    % ss11: alternative “1”
    % dlig: st ligature
    % liga=0: disable standard ligatures (see instrument name)
  }
}

\relative {
  \set Staff.instrumentName = "Afl. in G"
  \repeat unfold 3 { R1*10 \break }
  \tempo 8 = 36
  \tuplet 13/8 { c'8-"sempre stacc." d e f g a b c d e f g a }
  b1 c-"½ Va. + Vl. 1"
}
