I came to this snippet that worked for me:

    Shadowbox.init({ skipSetup: true });

    window.onload = function() {
        var $body = $('body'), $html = $('html');
        var scrollTop = 0;

        Shadowbox.setup("your selector",{
            onOpen:function(){
                if (window.innerHeight < window.outerHeight) {
                    scrollTop = ($html.scrollTop()) ? $html.scrollTop() : $body.scrollTop();
//                    $html.addClass('noscroll').css('top',-scrollTop);
                    $body.addClass('noscroll').css('top',-scrollTop);
                }
            },
            onClose:function(){
                $body.removeClass('noscroll').css('top','auto');
                $('html,body').scrollTop(scrollTop);
            }
        });
    };

(this is using the jquery-adapter,css-selector and delayed setup as documented)
