--bytes is equivalent to --apparent-size --block-size=1; this is --documented.
--human-readable is equivalent to --block-size=human-readable; this is
--not documented, which is a documentation bug. The later implicit
----block-size option wins, which explains the behavior you observe.
I also dislike it when option order affects behavior. Perhaps "du"
should complain about inconsistent options like that?
But if we leave the behavior alone, at least it should be documented
correctly. Here's a proposed patch to document the current behavior
more accurately, which is a minimal fix for now.

* doc/coreutils.texi (Common options): Mention that -h and
--human-readable are equivalent to --block-size=human-readable.
Documentation problem reported by Steve Ward in
<http://lists.gnu.org/archive/html/bug-coreutils/2007-06/msg00007.html>.
(du invocation): Use optSi rather than duplicating the macro's
contents (incorrectly, since we claimed a "B" was output).
