Please try:

class SpecificPriceRule extends SpecificPriceRuleCore
{
    public $lang_shop;
	
	public function __construct($id = null, $id_lang = null)
    {
		self::$definition['fields']['lang_shop'] = array('type' => self::TYPE_INT, 'shop' => true, 'validate' => 'isInt');
		parent::__construct($id, $id_lang);
	}
}
