If it is mere presence or absence of the header, not the string it carries, try
'def' instead of 'eq' as in;

quarantine:
driver = accept
transport = quarantine_delivery
condition = "${if def:header_X-Junk:{1}{0}}"

W/R the other snippets - I am not certain that you are setting-up address_data
and testing its content in the appropriate place or sequence. Or even CAse.

You may be more predictably served with use of acl_m variables.

Simply set up the selective steering parameters in acl's before entering the
router/transport sets.
