First it sounds like you don't really know what is in $score[0] (note not @score[0], though that may work). To get around this, 

use Data::Dumper;
print Dumper(\@score);

This will tell you what is actually in @score, where the first element will be $score[0].

Also, an array doesn't really contain another array. arrays can only contain scalars, though one type of scalar is a refrence, which can be thought of as a pointer to another array. If $score[0] is such a reference to an array, the correct notation is: 

@sorted= reverse sort { $a <=> $b } @{$score[0]};

This properly de-references the referance to feed an array into the sort.
