ok, I read about most of my questions and I think I understand them some but I still have an issue with understanding the error check portion here. don't know what this does

return $numbers{$a} <=> $numbers{$b}; #I guess it's checking against e
+achother...but how? is this a subroutine somewhere in a library/modul
+e??

after reading, this is still a little vague. I have issues understanding when to use the [] vs (). any clarification will be appreciated. 

$hash{$ita}[0]=$spa; #here we assign has_ref $span value address to fi
+rst position in array

for my $ita (sort { sort_italian() } keys %hash) #here ?? adding value
+ to array? am I right? not sure...
