neat stuff.
8: Comments : you seem to never use $length for anything interesting -- just as an added layer of complexity to your %word hash. You can remove it when referring to %words keys and achieve the same results :
push @{$word{$sorted_word}}, $_;
and so on.
Also, you can replace 
@most_ref=();
push @most_ref, \@{$word{$length}{$sorted_word}};

with 
@most_ref=(\@{$word{$sorted_word}});
