Not 100% sure ... but I would think to access a row it may be as simple as:

my %row = $hashes[cnt];

where cnt is the row that you want to access.  Or even better:

foreach my %row (@hashes){
  #then access each item in the hash with $row{qty}, or 
  #go through all the keys using "foreach my $key (sort keys %row)"
}
