To set the staff-size for a \book do
#(set-global-staff-size n1)
\book { }
#(set-global-staff-size n2)
\book { }

Doing
 \book { \paper { #(layout-set-staff-size n) } ... }
is neither recommended nor documented.
Rather the usage of #(layout-set-staff-size n) in a score-layout
_is_documented and works fine with note-by-number, afaict.
See the examples of
https://sourceforge.net/p/testlilyissues/issues/5122/

 To use
\book { \paper { #(layout-set-staff-size n) } ... }
may be a feature-request then.
