Ilya_Ru,
встроил в плагин, использовать

class="height"

нет необходимости, но лучшее решение это css, a не js.

(function($) {
    function setEqualHeight(columns) {
        var tallestcolumn = 0;
        columns.each(function() {
            currentHeight = $(this).css({
                height: ""
            }).height();
            if (currentHeight > tallestcolumn) tallestcolumn = currentHeight
        });
        columns.height(tallestcolumn)
    }
    $.fn.tabulous = function(options) {
        var settings = $.extend({
            effect: "scale"
        }, options);
        return this.each(function() {
            var parent = $(this),
                ul = $(">ul", parent),
                links = $(">li a", ul),
                block = $("> div", parent),
                divs = $("> div", block),
                hide = "hide" + settings.effect,
                show = "show" + settings.effect;
            ul.append('<span class="tabulousclear"></span>');
            divs.css({
                "position": "absolute",
                "top": "10px",
                "left": 0,
                "right": 0
            }).addClass("make_transist");
            block.addClass("transition");
            links.each(function(indx, a) {
                var a = $(a);
                a.on("click", function(event) {
                    event.preventDefault();
                    links.not(a.addClass("tabulous_active")).removeClass("tabulous_active");
                    var div = divs.eq(indx);
                    divs.removeClass(show).not(div.addClass(show)).addClass(hide);
                    block.height(div.height())
                })
            }).eq(0).click();
            setEqualHeight(links);
            $(window).resize(function() {
                block.height(divs.filter("." + show).height());
                setEqualHeight(links)
            })
        })
    }
})(jQuery);
