"I want to keep the keys/values in the same order for every array element in an AoH ref."

You just cant do that. You could instruct data dumper to PRINT them in sorted order (local $Data::Dumper::Sortkeys=1;), or you could program your own print loop to print them in a certain order, 

use strict; use warnings; 
my $data=

[
    {
        'lastname'  => 'Smith',
        'city'      => 'Chicago',
        'state'     => 'IL',
        'firstname' => 'Jim'
    },
    {
        'city'      => 'Cleveland',
        'state'     => 'OH',
        'firstname' => 'Susan',
        'lastname'  => 'Jones'
    },
    {
        'state'     => 'FL',
        'lastname'  => 'Waters',
        'firstname' => 'Sam',
        'city'      => 'Miami'
    }
];

my @order=qw/firstname lastname city state/; 
my $rowct=0; 
for my $row (@$data) { 
  printf "%5i \n",$rowct++; 
  for my $ordername (@order) { 
    printf " %20s %-20s \n",$ordername,$row->{$ordername}; 
    }
  }

but you cannot make perl keep them in any sort of "order" than the one it decides on.
