That sounds like a bug (or missing feature) to me:
dired-do-rename-regexp is supposed to be 100% compatible with
query-replace-regexp, as far as regexp replacement goes.

The regexp magic from query-replace-regexp is implemented in a two-step
process: first the interactive form translates such elements into a
replacement list of a specific form rather than a replacement string,
and then perform-replace works using this list.

The generated list (and the code processing it) heavily relies on
working in a buffer whereas dired-do-rename-regexp basically works on a
string.  Making the additional magic available generally instead of just
to query-replace-regexp itself would require some amount of work, not
least of all because one would need to design a reasonable interface for
this functionality which is, at the current point of time, more or less
a hack inside of replace.el.

If we don't make them use the same underlying mechanism,
could we at least make them handle \# compatibly?
