I think you need
SELECT * FROM
(
SELECT ... FROM participants
WHERE typenr=1 AND <eligibility>
UNION
(SELECT ... FROM participants
WHERE typenr=2 LIMIT 172)
) ss
ORDER BY zip;
Not sure if the inner set of parens is essential, but it might be.
The outer SELECT superstructure is definitely necessary to give a
place to hang the ORDER BY on.
