  `id` int(10) unsigned NOT NULL auto_increment,

Answer 1

As the other answer mentions: the query you posted has nothing about what order you'd like your results, just which results you'd like to get.

To order your results, I would use ORDER BY FIELD():

SELECT * FROM foo f where f.id IN (2, 3, 1)
ORDER BY FIELD(f.id, 2, 3, 1);

The argument list to FIELD can be variable length.
