MySQL - get sum() grouped max() of group -

i have table structure below. each row 1 played game, each person can play many or none times in each month.

 id  |  person  |  score  |   date  | ------------------------------------ 1   |    32    |  444    | 2011-05 | 2   |    65    |  528    | 2011-05 | 3   |    77    |  455    | 2011-05 | 4   |    32    |  266    | 2011-06 | 5   |    77    |  100    | 2011-06 | 6   |    77    |  457    | 2011-06 | 7   |    77    |  457    | 2011-06 | 8   |    65    |  999    | 2011-07 | 9   |    32    |  222    | 2011-07 | 

i trying each person sum of best score in each month. s result of above should be:

  person  | sum(ofbestofeachmonth) ---------------------------------   32     |  932   65     |  1527   77     |  912 

i know how fetch bests scores per userin month or range

 select person, date, max(score) tabgames month(date) = 6 group person having (score>0) 

because need in end output per quarter of year, fetching best each month , outside mysql adding.

now reading group-wise max , still try excpected results. help

subqueries:

select person, sum(best)     (select person, max(score) best     tabgames     month(`date`) >= 1 , month(`date`) <= 6      group person, month(`date`)) bests group person 

now subquery grouped person , month(date), return row each month.
