If you are getting colored "%{" and "%}" in your prompt, then you
probably just need to make sure that the prompt_percent option is set.

I started a thread a couple weeks ago about a shell-script I was working
on that does an abbreviated suspended-jobs-list on the command-line,
which has similar issues to your own (except that, I'm also keeping the
whole script compatible with bash and ksh as well). Bash uses "\[" and
"\]" (without requiring an option to be set); and ksh uses... an
abomination that involves carefully selecting a control character that
doesn't print anything on any terminal you wish to support. :)
