Sorting with respect to the first column is a bit more involved compared to your code, see below. Sorting only part of the array can be achieved using array slices:

@AoA = (
           [ 0.5, "b1", "c0" ],
           [ 0.4, "b1", "c1" ],
           [ 0.7, "b2", "c2" ],
           [ 0.3, "b3", "c3" ],
           [ 0.6, "b3", "c4" ],
 );

@AoA[2..$#AoA] = sort { $a->[0] <=> $b->[0] } @AoA[2..$#AoA];
print Dumper \@AoA;
