I have tried so many different permutations of setting relative or
absolute font size, having one or two definitions for bookTitleMarkup,
placing things in different scopes etc. that I have lost track of what
didn't work - which was everything until an hour ago.  I have now found
something that does work, ungainly though it undoubtedly is.

What I now have, basically, is this:

\version "2.18.0"

#(set-global-staff-size 16)

\book {
  %This is the score
  \paper
    bookTitleMarkup = \myBookTitleMarkupSixteen
  }
  \score  { }
  \layout { }
}

#(set-global-staff-size 20)

\book {
  %This is the first of the instrumental parts
  \paper
    bookTitleMarkup = \myBookTitleMarkupTwenty
  }
  \score  { }
  \layout { }
}

In the 2 different bookTitleMarkup definitions, I have used proportional
measurements, corresponding to the 5/4 ratio of the staff sizes in the
score/parts.  So I have (baseline-skip . 5) and (baseline-skip . 4)
respectively.  I specify the size of each item using \fontsize, with a
difference of 2 for each corresponding item in the score and part
definitions respectively  - e.g., where I have \fontsize #7 in the
definition for the score, I have \fontsize #5 in the definition used for
the parts (this difference of 2 corresponds to the statement made in the
Learning Manual section 4.3.2, where it says that 1 step is
approximately equivalent to 12%.)

The result is that the printed output is virtually identical in the
score and parts, despite the difference in staff size in the music that
follows.

I dare say there is a prettier and more concise way of doing this, but
at least I now have something that works!
