Thanks for the report.  Initially `isearch-forward' is nil, so M-% tries
to search backward going through the minibuffer history (thus it uses the
global value of `isearch-forward' in `minibuffer-history-isearch-search').

It is evident now from your report that the search space for replacements
should be narrowed to the strict set of search functions defined in isearch.el.

This is a regression, so I propose to install the following patch to the
emacs-24 release branch:
