What do you want to sort it on?

Sorting won't change the data, only its order.  If you want to change 
the order of the hashrefs in the array based upon the value of key1 
then you can do:

   @array = sort { $a->{key1} cmp $b->{key1} } @array

There's no way sorting the array could break apart the entries in the 
hashrefs.
