how to sort a birthday list ?

Hi !

there's a nice query for retrieving the people who have their birthday 
in the next n days: (taken from Joe Celko's SQL for Smarties, 1st Ed., 
p. 76)

SELECT *
FROM Persons
WHERE EXTRACT( YEAR FROM AGE(dateofbirth) ) < EXTRACT( YEAR FROM AGE( 
CURRENT_DATE+60, dateofbirth ) )

... but how do I sort the list ?
