Can't do all three patches

On the August 6 dev version (/* $Id: quiz.module,v 1.86.2.18 2007/08/06 23:35:32 kscheirer Exp $ */) I can add the patches

- quiz_anonymous_caching.patch
- quiz_edit_questions_2.patch

but not

- quiz_result_options.patch

Here is the output of a dry run of that third patch:

I looked at the HEAD version to see if it included all three, but it looks several months old.
