directive options go before the % format codes. The above says that
helper command line is:
"/somedir/script.sh ttl=0 negative_ttl=0 grace=0 children-startup=1
children-max=1"

tcp_outgoing_address is a "fast" group ACL check. It can use previously
cached results or schedule lookups, but cannot wait for them to
complete.
If you get that config right your *=0 settings will prevent the
triggered lookups from caching any results, and the new lookup can't be
waited for so there is never any match possible.

The "" quoted part is the lookup being passed to the helper. So either
you actually used %SRC or %DST etc in your external_acl_type format or
those lines are not related toe the tcp_outgoing_address lookups.
