You may want to try something like the following, using the same expressions in the ORDER BY clause as in your WHERE clause:

SELECT    *
FROM      your_table
WHERE     field_1 = 100 OR
          field_2 = 200 OR
          field_3 = 300
ORDER BY  field_1 = 100 DESC,
          field_2 = 200 DESC,
          field_3 = 300 DESC;
