Сделал так:

app.ratingTooltipTpl = function (e) {
        var res = "<div id='set-rating" + e.chainId + "'>";
        var rate = e.rating;
        var spanArr = [];

        for (var i = 1; i <= 5; ++i) {
            spanArr.push("<span rate=" + i + " chainId=" + e.chainId + " class='action-tooltip rating-empty' onclick='setRating(this)'></span>");
        }

        switch (rate) {
            case 1:
                spanArr[0].replace("empty", "yellow-star");
                break;
            case 2:
                spanArr[0].replace("empty", "yellow-star");
                spanArr[1].replace("empty", "yellow-star");
                break;
            case 3:
                spanArr[0].replace("empty", "yellow-star");
                spanArr[1].replace("empty", "yellow-star");
                spanArr[2].replace("empty", "yellow-star");
                break;
            case 4:
                spanArr[0].replace("empty", "yellow-star");
                spanArr[1].replace("empty", "yellow-star");
                spanArr[2].replace("empty", "yellow-star");
                spanArr[3].replace("empty", "yellow-star");
                break;
            case 5:
                spanArr[0].replace("empty", "yellow-star");
                spanArr[1].replace("empty", "yellow-star");
                spanArr[2].replace("empty", "yellow-star");
                spanArr[3].replace("empty", "yellow-star");
                spanArr[4].replace("empty", "yellow-star");
                break;
        }

        var spans = spanArr.join();
        res += spans;
        res = res + "</div></br>Баллы:<span id='rating-rate" + e.chainId + "'>"+rate+"</span>";
        return res;
    };

Между спанами запятые выводятся...
