You should provide sortBy with an appropriate compare function, e.g.
comp (a,b) (c,d) | a > c = GT
| -- etc etc.
or go with the manky but working hack:
λ> :m Data.List
λ> sortOn (\(a, b) -> b*(-100) + fromEnum a) [('r',2), ('c',2),('a', 2),
('b',3), ('f',2)]
[('b',3),('a',2),('c',2),('f',2),('r',2)]

It also runs on windows but needs proper setup before hand.
That is, it needs to be installed outside of Haskell and then you can
install the Haskell bindings.
