вы должны использовать систему cron Magento и вызвать метод пользовательской модели:

<config>
    <!--...-->
    <crontab>
        <jobs>
            <company_test>
                <schedule>
                    <cron_expr>0,15,30,45 * * * *</cron_expr>
                </schedule>
                <run>
                    <model>test/testmodel::testMethod</model>
                </run>
            </company_module>
        </jobs>
    </crontab>
</config>

Когда это будет сделано, вы можете обновить опцию конкретного продукта, используя модельMage_Catalog_Model_Product_Option. Я не знаю, как создается CSV, но алгоритм может быть примерно таким:

// foreach option
/** @var $opt Mage_Catalog_Model_Product_Option */
$opt = Mage::getModel('catalog/product_option');
$opt->setProduct($product);

$optionArray = array(
    'is_delete' => 0,
    'title' => 'Blabla',
    'previous_group' => '',
    'previous_type' => '',
    'type' => 'field',  //can be radio, drop_down, file, area...
    'is_require' => 0,
    'sort_order' => 42,
    'values' => array()
);

$opt->addOption($optionArray);
$opt->saveOptions();
// end foreach
