jqueryで多次元配列のｿｰﾄ方法を教えてください

var name = [
[0,6666,"saburo"],
[0,2222,"tarou"],
[1,4444,"hime"],
[0,5555,"zirou"],
[1,3333,"hanako"],
[0,6666,"saburo"]
];

name[1]が若い数字順､且つ､name[0]が0を優先して並び変える方法を教えてください｡

並び替えごをこのようにしたいです｡

var name = [
[0,2222,"tarou"],
[0,5555,"zirou"],
[0,6666,"saburo"]
[0,6666,"saburo"],
[1,3333,"hanako"],
[1,4444,"hime"]
];

var before = [
 [0,6666,"saburo"],
 [0,2222,"tarou"],
 [1,4444,"hime"],
 [0,5555,"zirou"],
 [1,3333,"hanako"],
 [0,6666,"saburo"]
];

after = before.sort(function(a, b) {
 if (a[0] !== b[0]) {
 return a[0] - b[0];
 } else {
 return a[1] - b[1];
 }
});
