Actually, SQL Server does not sort at all. It just retrieves the rows
in the order which happens to be most efficient.

As an alterantive to Dan's suggestion, this may or may not fit better
to your actual problem:

SELECT STRINGTEXT, TOKENID
FROM WEBSTRINGS
WHERE TOKENID IN (6,20,234,19,32,4,800,177)
ORDER BY CASE TOKENID
WHEN 6 THEN 1
WHEN 20 THEN 2
WHEN 234 THEN 3
-- etc
END
