Tested on 5.0.8 and 5.2

I think the real point, now Bart has pointed out what the problem is, is
that you need to triple backslash the "`", or more simply use a single
quote around the lot together with a single backslash. With
promptsubst, you need vared to see the backslash before the "`". Or
vared_prompt='The string I want the user to see'
vared -cp ${(q)vared_prompt} user
(Refer back to http://xkcd.com/1638/ again if you've forgotten.)

Eyugh. Nope.
% foo='This prompt "contains" `surprises'\''?'
% vared -cp ${(q)foo} stuff
This\ prompt\ \"contains\"\ `surprises\'\?
To automate probably better off with
vared_prompt() {
emulate -L zsh
unsetopt promptsubst
vared -p $1 $2
}
vared_prompt 'The literal prompt' the_variable
