AFAIR, output-scale is changed in \score markups.  That changes the
behavior of dimensions in those: I implemented an issue to fix problems
here but I was basically flying blind.  Let's see.  There is

    This change modifies the fix for issue 677 to avoid scaling problems
    when employing $(ly:grob-layout grob) in the \layout of a score
markup.

    Issue 677: \score markup confuses paper settings
