Umm... ZF does *not* set any headers by default, and certainly not any
caching headers. Your culprit is most likely your Apache install.

This *should* work in ZF -- we make use of the response code and raw
header accessors in the ErrorHandler plugin with no issues. Again, my
guess is that your web server is overriding this.
