javascript - 複数の列をソートするTaffy DB

Question

そのため、Taffy データベースを複数の列で並べ替えようとすると、予期しない結果が得られます。この例:

<script src="./taffy/taffy.js"></script>
<script>

    var myTaffyDB = TAFFY([
        {"foo":"bar","letter":"A","number_01":48,"number_02":6},
        {"foo":"bar","letter":"S","number_01":49,"number_02":2},
        {"foo":"bar","letter":"Q","number_01":49,"number_02":3},
        {"foo":"bar","letter":"W","number_01":49,"number_02":4},
        {"foo":"bar","letter":"P","number_01":49,"number_02":5},
        {"foo":"bar","letter":"T","number_01":49,"number_02":6},
        {"foo":"bar","letter":"W","number_01":49,"number_02":7},
        {"foo":"bar","letter":"Q","number_01":49,"number_02":8},
        {"foo":"bar","letter":"A","number_01":49,"number_02":9},
        {"foo":"bar","letter":"C","number_01":49,"number_02":10},
        {"foo":"bar","letter":"B","number_01":50,"number_02":1}
    ]);
            var tempResultsArray = myTaffyDB({"foo":"bar"})
                .order("letter","number_01","number_02")
                .select( "letter", "number_01", "number_02")
            ;
        console.log( 'tempResultsArray: ' + tempResultsArray );

    </script>

以下を生成します。

A,48,6,A,49,9,B,50,1,C,49,10,P,49,5,Q,49,8,Q,49,3,S,49,2,T,49,6,W,49,4,W,49,7

Q の結果は 49,8、次に 49,3 の順序でソートされることに注意してください。ただし、順序呼び出しでは、文字ごとにグループ化し、次に number_01、次に number_02 と指定しています。

これを構築する方法に何か欠けているのでしょうか、それとも Taffy の注文結果に何らかの制限がありますか?
