Look at the List.sort type:

  ('a -> 'a -> int) -> 'a list -> 'a list

the first "argument" required by List.sort have type "function that
takes two arguments of the same type and return an int".
The type of compare is:

  'a -> 'a -> int

you then have to pass the function compare itself without applying it
(as I saw in one of your example).
This is a sample usage:

  List.sort compare [3;2;1]

Indeed "List.sort compare" have type

  'a list -> 'a list

Cheers.
