I checked how far out the scaling of the markup score was prior to 677: by 
ruler I measured it as being a factor of 1.76.  The command-line output 
shows \cm as being 10 for the "normal" layout, and 5.69 for the \layout with 
$(ly:grob-layout grob).  The ratio between these is 1.757.  So it seems 
clear that the problem is related to 677, although I clearly have no idea 
what's going on.

I can post this as a bug, but I'm guessing it would be tricky to fix.  Would 
you object to scaling the dimensions of the incipit (in the incipit code) 
line-width and indent by the 1.76 factor, to work round the problem?
