I do not fully understand exactly what you want... but if you want one score 
for each scale, then put one score with one scale in each file (like "\score 
{\notes {\key c \major c d e f g a b c'}}"), and then create a file all.ly 
containing
\include "c_major.ly"
\include "c_minor.ly"
...
and so on, 30 lines.

However, in this particular case it would be even more clever to make use of 
variables and \transpose, i.e. define the scale exercise for just one key 
once (like MajorScale = \notes {\key c \major c d e f g a b c'}) and then use 
"\transpose f' \MajorScale" to get a f major scale. This will transpose the 
key as well as all the notes to the new key.
