Answer 1

Following will do:

SELECT *
FROM _table
ORDER BY SUBSTR(DATE('NOW'), 6)>SUBSTR(birthdate, 6), SUBSTR(birthdate, 6)

Check it in SQL Fiddle.

SUBSTR(date, 6) will remove year part from date. Birthdates must be sorted in MM-DD, but first should be shown those which will happen after today, and then those which happen before today.

SUBSTR(DATE('NOW'), 6)>SUBSTR(birthdate, 6) will return 0 for birthdates MM-DD greater or equal to today MM-DD, 1 otherwise. So, first expression will ORDER past dates after comming date. Second parameter just ORDER dates by MM-DD.
