If then you suspect split function, then check what you are getting for each split "action" ( using print ), before assigning them to other variables. like so: 

 print join "\n",split /\t/, $hash{$key}, 7;

See if you have 7 seperate values. If not, then one can say try "\s+" in the split function, instead of the "\t" like so: 
 print join "\n",split /\s+/, $hash{$key}, 7;

If that works, then :-)! You got it!!!
