Old school way (Beware! Ternary operator ahead!):

a = (1..96).to_a.reverse
a.each_with_index{|x,i|print x,i%12==11?"\n":"\t"}

Idea:

Iterate x over all elements of a
. print x
. is it value number eleven (the twelveth) in the row?
. . if so break line
. . if not jump to next tabulator
. condition ends
iteration ends
