Don't use %{%}.  They are used to indicate a sequence that doesn't move
the cursor, such as a colour escape sequence.  Also, $() is recommended
over ``, but in any case jobs doesn't work in a subshell.  A possible
approach would be to put something in precmd (a function run before each
prompt) like this:

function precmd {
  if jobs % >& /dev/null; then
    psvar=("*")
  else
    psvar=("")
  fi
}

And then put "%1v" in your prompt, for example:

PROMPT="%1v> "

and this will put a * in your prompt if there are any background jobs.
You can substitute any other sequence.

I think I might start using this myself.
