Добре, ако това помогне на някой друг, успях да постигна това, което исках, като направя това:
SELECT *,
CASE WHEN wm = 'foot locker' THEN 1 ELSE 0 END AS score,
MATCH (`wm`, `locn`, `gns`) AGAINST('foot locker') AS score2
FROM
`example_table`
WHERE
MATCH (`wm`, `locn`, `gns`) AGAINST('foot locker'))
ORDER BY
score DESC, score2 DESC;
