If you're using Perl anyway, then do it with two selects and sort in
perl. 200 lines is nothing for perl.
Or you can emulate UNION with temporary table.
CREATE TEMPORARY xxx SELECT ...
INSERT xxx SELECT ...
SELECT xxx ...
Or...
CREATE TABLE nums (position INT UNSIGNED NOT NULL AUTO_INCREMENT);
fill it with 1..200 (you can do it only once, of course) and
SELECT position,title FROM nums,books WHERE position1=position OR
position2=position ORDER BY position;

I can understand that :-)
