[Haskell-beginners] Down in Data.Ord vs GHC.Exts

While attempting to do some sorting, I ran across Down. The docs:
http://hackage.haskell.org/packages/archive/base/latest/doc/html/Data-Ord.html#t:Downsay
it's in Data.Ord, but GHCi 7.4.1 complains the Down data constructor
isn't in scope, but if I import GHC.Exts (
http://hackage.haskell.org/packages/archive/base/latest/doc/html/GHC-Exts.html#t:Down),
I get the constructor I expect.
Are the docs wrong? Or is there something I'm not doing right to get Down
exported from Data.Ord? Or other things to check?
Thanks,
Matthew
