I think perhaps you have misunderstood what I was suggesting. If the
SQL in your original post works, then my suggestion will also work.
In my haste to reply I accidentally omitted the where clause of the
query.

Wouldn't this (full example) work?

SELECT
name,zip,
(SELECT zip = '04317') as zipmatch
FROM
dem.urb
WHERE name ilike 'lei%'
ORDER BY zipmatch DESC, name;

If your code runs, this will too.
