+You have 3 lists that you want to sort "relative" to each other,
+for example, picturing each list as a row in a 3x3 matrix: sort it by columns

+########################
+If the input lists are
+########################
+
+ list1 = ['c','b','a']
+ list2 = [6,5,4]
+ list3 = ['some-val-associated-with-c','another_val-b','z_another_third_val-a']
+
+########################
+the desired outcome is:
+########################
+
+ ['a', 'b', 'c'] 
+ [4, 5, 6] 
+ ['z_another_third_val-a', 'another_val-b', 'some-val-associated-with-c']
