I have detailed this in a blog post: http://chadkuehn.com/jquery-validate-select2/

When you place a Select2 on a SELECT tag it hides the original element. So in the validation plugin you must adjust the proper wrapping markup when highlighting and unhighlighting.

    highlight: function (element, errorClass, validClass) {
        var elem = $(element);
        if (elem.hasClass("select2-offscreen")) {
            $("#s2id_" + elem.attr("id") + " ul").addClass(errorClass);
        } else {
            elem.addClass(errorClass);
        }
    },

    unhighlight: function (element, errorClass, validClass) {
        var elem = $(element);
        if (elem.hasClass("select2-offscreen")) {
            $("#s2id_" + elem.attr("id") + " ul").removeClass(errorClass);
        } else {
            elem.removeClass(errorClass);
        }
    }
