I assume that some scores are meant to have a smaller staff size than 
others, hence the need for a separate multiplier.
Say score A has "design size" ("natural size"? whatever) of 16 and 
should be scaled up to 1.25*16 = 20, while score B with a smaller piece 
has "design size" of 20 and should be scaled up by the same factor to 
1.25*20 = 24.

Anyway, regardless of the use case, the following piece of code should 
do it:

#(define design-staff-size 16)
#(define staff-size-multiplier 1.25)
#(set-global-staff-size (* design-staff-size staff-size-multiplier))

The "(* variable multiplier)" part is Scheme syntax for "apply the 
multiplication function to design-staff-size and staff-size-multiplier". 
The definitions of the two variables can be anywhere before the call to 
set-global-staff-size, including includes. IIUC, this is what you want 
to achieve?
