None of these is tests_require.  The above lists the contents of  
install_requires and the test extra.  zope.tal is odd because it  
lists the same values in tests_require and install requires.  Try  
putting something else in tests_require and see if you see it show up.

I know that the contents of tests_require isn't saved because I  
*tried* to get buildout to use it and asked about it on the distutils  
sig:

   http://mail.python.org/pipermail/distutils-sig/2007-January/ 
007083.html

Of course, something could have changed since then, but I doubt it.

Again, I believe you are mistaken.
