You use an array of array(refs):
my @array = ();
$array[0] = [ 1, 2, 3];
$array[1] = [ 4, 5, 6];
#...
$array[77] = [232,233,234];
You can then access individual elements with the following syntax:
print $array[3][1]; # prints 11

my @sorted_array = sort { $a->[0] <=> $b->[0] } @array;
(You may want to use 'cmp' instead of '<=>', since you want to sort
ASCIIbetically.)
