It works for me, but it does seem it has some problems. It seems cmd
doesn't terminate the pipe nicely and sort throws an ugly error after
cmd exits. It also kind of freezes after the command if you run it
interactive. Cmd doesn't play nicely with non-windows executables, or
the piping stuff is not properly implemented.

$ ls
bar  baz  foo  x.cmd
$ wine cmd /c x.cmd

Z:\home\octav\x>(for /d %i in (*) do echo %i) | Z:\usr\bin\sort
foo
bar
baz
$ Z:\usr\bin\sort: read failed: -: Input/output error

I wasn't even remotely suggesting committing such an atrocity! It was
just to make sure the commented tests you commit are OK, but I guess
you can also use native sort.exe. Come to think of it, if you add
Z:\usr\bin to PATH it should work even better...
