Random output in LilyPond Log

[Freeman Gilmore]

I am using Frescobaldi and studying the Scheme Book.    When I compile,

mylist = #( list 'red  random 12 )
#(display mylist)

I get two different results in the LilyPond Log, see below.    The line, 

(red #<primitive-procedure random> 12)

changes  positions randomly when compile.   Would someone explain?

Thank you, ƒg
