What is "the sort order"?

I SUPPOSE (from the example) that the tuples are compared lexicographically?

If yes, might I suggest mentioning this explicitely in the docs?

IMHO it'd be better if the reader wouldn't have to infer such info from the examples or own testing but just read it...

まず xml/System/Tuple`2.xml と、リンク先の Tuple.IComparable.CompareTo(Object) ページを開きます。辞書式比較に関する issue の質問に照らして既存の記述を確認し、「sort order」が明示されるようにドキュメントを更新します。読者が例から推測しなくても理解できれば完了です。
