If this is an exercise to demonstrate random numbers, I wonder if it 
needs more parentheses.

% CODE
\version "2.19.80"
mylist = #(list 'red (random 12))
#(display mylist)
% END CODE

If I run it that way in Frescobaldi, it always returns: (red 3)

If I use lilypond scheme-sandbox, I get things like this:

(red 3)

(red 4)

(red 1)

(red 9)

ACCOUNTING TROLL: This is our random number generator... nine nine nine 
nine nine
DILBERT: That doesn't sound random to me.
ACCOUNTING TROLL: That's the trouble with random numbers. You never can 
tell.
