You should only need one ORDER BY clause at the end of the whole query:
(SELECT...)
UNION ALL
(SELECT...)
UNION ALL
(SELECT...)
ORDER BY...
I'm not sure if this syntax is portable to other SQL-based DBMSes, though. I'm
certain that one system we use at work doesn't support it, but it's kind of a
dinosaur so I don't like to draw too many conclusions from what it doesn't
support.
