hot to sync Product price from pricebook?

This could be solved in Drupal 6 in the following way:

/**
 * Bulk price import handler.
 */
function uc_sf_product_salesforce_bulk_price_import_submit($form, &$form_state) {
  $fieldmap = variable_get('uc_sf_order_order_product_export_fieldmap', FALSE);

  foreach ($form_state['values']['nodes'] as $nid => $prices) {
    $node = node_load($nid);
    foreach ($prices as $currency => $data) {
      if ($currency == variable_get('uc_currency_code', 'USD')) {
        $node->sell_price = $data['price'];
      }
      elseif (module_exists('uc_multicurrency')) {
        $node->multicurrency[$currency]['sell_price'] = $data['price'];
      }

      // Store the pricebook ID
      if ($fieldmap) {
        salesforce_api_id_save('uc_sf_pricebook_' . $currency, $nid, $data['sfid'], $fieldmap);
      }
    }
    node_save($node);
  }

  drupal_set_message(t('Product prices have been imported from Salesforce.'));
  drupal_goto('admin/store/products');
}

/**
 * Implementation of hook_fieldmap_objects_alter().
 */
function uc_sf_product_fieldmap_objects_alter(&$objects) {
  // makes the same fields available for export to a contact as they are to an order
  $objects['drupal']['uc_order_products']['fields']['pricebook_sfid'] = array(
    'label' => t('Pricebook Entry Salesforce ID'),
    'group' => t('Order Line Item Information'),
    'type' => SALESFORCE_FIELD_SOURCE_ONLY,
    'export' => '_uc_sf_product_export_pricebook_sfid',
  );
}

function _uc_sf_product_export_pricebook_sfid($product) {
  static $currency = array();

  if (!isset($currency[$product->order_id])) {
    $order = uc_order_load($product->order_id);
    $currency[$product->order_id] = $order->currency;
  }

  $pricebook = salesforce_api_id_load('uc_sf_pricebook_' . $currency[$product->order_id], $product->nid);
  return $pricebook->sfid;
}
