Here's a stab at the first one: 
sub locationscore {
  my $self = shift;
  my $rows = shift;
  my %locations;
  for my $row (@$rows) {
    my $sum = 0;
    for (1..$#$row) { $sum += $row->[$_] };
    if (!defined($locations{ $row->[0] } || $sum < $locations{ $row->[
+0] } ) {
        $locations{ $row->[0] } = $sum;
    }
  }
  $self->normalizescores(\%locations, ...);
}

Update: Fixed logic error in setting of $locations{ $row->[0] }. I've taken a little liberty with the logic. To make it conform strictly with the original python coding, just add 
$locations{ $_->[0] } = 1_000_000 for (@$rows);

right before the for loop.
