The logic for multiple sorting is as follows, 

my @sorted = sort {
    $a->{'level'} <=> $b->{'level'}
    ||
    $a->{'department'} cmp $b->{'department'}
} @array;

That works by the lazy evaluation of logical operators. If comparison by level is not a tie, the department comparison is not made.
