Perl的哈希值没有秩序。您必须将它们切换到阵列，或（当你需要遍历散列例如）在他们使用排序。

Perl hashes do not have order. You must either switch them to arrays, or sort them upon usage (e.g. when you need to iterate over that hash).

第一种解决方案可能看起来像：

The first solution could look like:

@aoh =(
 [{ 4 => 8 }
, { 5 => 9 },
, { 3 => 15 }
 ],

...

第二个解决方案是：

foreach $subhash (@aoh) {
   foreach $sorted_key (sort { $subhash->{$a} <=> $subhash->{$b} } keys %$subhash) {
      # Do something with $subhash->{$sorted_key};
   }
}
