I think you should probably change $WA{$key}{stgs} =(); to $WA{$key}{stags} =[];, i.e. setting stags to a array_ref and using the same key as your initialization (stags in place of stgs).

As well, in place of unshift @{WA{$key}{stags}} you should have unshift @{$WA{$key}{stags}}, repeating that change in the following lines.
