Solution from Raphaël Malié is almost perfect, but it needs evt.preventDefault() for touchend, otherwise it will generate a click on a link/button that is under clicked item.

    var movedWhildAutocomplete = false;
    $(document)
        .on('touchstart', '.ui-autocomplete li.ui-menu-item', function(){
            $(this).trigger('mouseenter');
            movedWhildAutocomplete = false;
        })
        .on('touchmove', '.ui-autocomplete li.ui-menu-item', function(){
            movedWhildAutocomplete = true;
        })
        .on('touchend', '.ui-autocomplete li.ui-menu-item', function(evt){
            if (!movedWhildAutocomplete) {
                var $el = $(this);
                if ($el.is(':visible') && $el.hasClass('ui-state-focus')) {
                    evt.preventDefault();
                    $el.trigger('click');
                }
            }
            movedWhildAutocomplete = false;
        });
