Encontrar valores iguais no array e somar os melhores pontos dos valores iguais

Preciso encontrar todos os valores iguais do player e da key '34MB' (exemplo)  e separar as 8 melhores pontuações se tiver + que 8, se não tiver + que 8 exibir os que tem e somar total_points desse player

OBS: o player 52586 está em outra key diferente '4M1' não pode somar os valores de keys diferentes, apenas das mesmas keys

Tenho essa array:

	Não sei como fazer isso... um exemplo, o player 52586 tem que ter 972 pontos na 34MB e 600 na 4M1.
