grep { $_->[2] =~ $rxExtract }
[download]

with

   sort { $a->[2] <=> $b->[2] }
[download]

Note that I have used a numerical comparison in the sort (<=>) just in case your second column has numbers of other than four digits. If there will always be only four digits you could use string comparison (cmp).

I hope this is of use
