Autovivification.

Change...

if(exists $ulm_keys{$h_tag}{$h_val}){....

[download]

... to ... 

if( 
    exists $ulm_keys{$h_tag} and 
    exists $ulm_keys{$h_tag}{$h_val}
) { ...

[download]

...and see if that fixes things. What's happening is that currently as you test for the existance of $h_val, $h_tag is created automatically whether or not $h_val exists.

Here is Uri Gutman's tutorial on the subject.
