Hashes have both keys and values; they arent stored by indices (like arrays). Perl stores the hash elements internally by calcing some values... As already described above, try something similar to

@sorted_keys = sort { $a <=> $b } keys %hash; 
#use { $a <=> $b } for numerical sorting
#use { $a cmp $b } for string sorting
foreach(@sorted_keys) { print $hash{$_}; }
