Thanks for all the help, this is what turned out to be the easiest fix,
Ovid's suggestion
use Data::Dumper;
use Tie::SortHash;
%hash = (
x=> 'line 1',
z=> [ 1, 2, 4],
y=> { file=> 'test.txt',
length=> 200,
type => 'ASCII'
},
a=> 'line 2'
);
tie %hash, 'Tie::SortHash', \%hash;
print Dumper(\%hash);
and all came out as I desired.
