I used

\version "2.19"
\include "openlilylib-master/editorial-tools/edition-engraver/definitions.ily"
\addEdition test
\editionMod test 1 0/4 test.Score.A \override NoteHead.font-size = 2
override-color = #red
tweak-color = #blue
colorOverride = […]  %%  full function definition would be here
\layout { \context { \Score \consists \editionEngraver test }}
\displayMusic { c’' }

The output remained the same (i.e., the NoteHead font-size did change).

Aha.  So in the console do you see something like:

 

(make-music

  'ContextSpeccedMusic

  'create-new

  #t

  'property-operations

  (list (list 'push

              'NoteHead

              2

              'font-size))

  'context-type

  'Staff

  'element

  (make-music

    'SequentialMusic

    'elements

    (list (make-music

            'NoteEvent

            'pitch

            (ly:make-pitch 0 0)

            'duration

            (ly:make-duration 2)))))

%%%

If so, the edition engraver is doing the equivalent of:

\new Staff \with { \override NoteHead.font-size = 2 }

{

  c'

}

and I may be able to get at that through 'property-operations.
