I would include an index range test to avoid a possible slew of warnings such as those generated by the OPed example code (numeric comparisons of non-numerics). (The pair of tests, of index and element value, could easily be encapsulated in a function.) 

c:\@Work\Perl>perl -wMstrict -MData::Dump -le
"use Data::Dumper;
 ;;
 my @arr = (
      [ 'A', 1, 0, 5, 6, 2 ],
      [ 'B', 3, 4, 5, 6, 7 ],
      [ 'C', 2, 4, 3, 5 ],
      [ 'D', 6, 7, 8, 8 ],
      [ 'E', 2, 5, 4, 5 ],
      [ 'F', 4, 3, 2, 2 ],
      [ 'G', 1, 2, 4, 5 ],
      [ 'H', 1, 4, 5, 6 ]
  );
 ;;
 my @rows =
   grep { (@$_ > 2 && $_->[2] > 4) && (@$_ > 4 && $_->[4] > 3) }
   @arr
   ;
 dd \@rows;
"
[["D", 6, 7, 8, 8], ["E", 2, 5, 4, 5]]
