You can try something like this... Live Demo

I made ​​some changes...

  1. Corrected the mistake :
    // before that I'm checking arrays and not a values of it...
    (!isNaN(a) && !isNaN(b)) to (!isNaN(a[0]) && !isNaN(b[0]))
  2. and to ignore case...
    aa = a[0].toString().toLowerCase(); bb = b[0].toString().toLowerCase();

===========================================================

arr.sort(function (a, b) {
    var aa, bb;
    if (!isNaN(a[0]) && !isNaN(b[0])) {
        return a[0] - b[0];
    } else {
        aa = a[0].toString().toLowerCase();
        bb = b[0].toString().toLowerCase();
        return (aa == bb) ? 0 : (aa < bb) ? -1 : 1;
    }
});

Use this code to sort your array..

var arr = [[0,"lol"],[6,"yo"],[5,"comon"]];

arr.sort(function(a, b) {
    if (a[0] == b[0]) {
        return 0;
    } else {
        return a[0] < b[0] ? -1 : 1;
    }
});
