This is quite nasty and clunky, but it should work. Create a temporary table, and insert the ordered list of IDs, as returned by Lucene. Join the table containing the items to the table containing the list of ordered IDs:

CREATE TABLE item (
    id INTEGER PRIMARY KEY ASC,
    thing TEXT);

INSERT INTO item (thing) VALUES ("thing 1");
INSERT INTO item (thing) VALUES ("thing 2");
INSERT INTO item (thing) VALUES ("thing 3");

CREATE TEMP TABLE ordered (
    id INTEGER PRIMARY KEY ASC,
    item_id INTEGER);

INSERT INTO ordered (item_id) VALUES (2);
INSERT INTO ordered (item_id) VALUES (3);
INSERT INTO ordered (item_id) VALUES (1);

SELECT item.thing
FROM item
JOIN ordered
ON ordered.item_id = item.id
ORDER BY ordered.id;

Output:

thing 2
thing 3
thing 1

Yes, it's the sort of SQL that will make people shudder, but I don't know of a SQLite equivalent for ORDER BY FIELD.
