I've added a custom attribute for all the categories. It's currently positioned as the first element in the list when you configure a category. How would I go about about changing it's position in the list? I've tried using the position key in the setup script, but alas no luck. It does get saved in the database, other than that it has no (visual) effect.
setup script:
<?php
/** @var Mage_Catalog_Model_Resource_Setup $installer */
$installer = $this;
$installer->startSetup();
$installer->addAttribute('catalog_category', 'custom_menu', array(
'type' => 'int',
'input' => 'select',
'source' => 'eav/entity_attribute_source_boolean',
'global' => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_STORE,
'required' => false,
'label' => 'Is Custom',
'default' => 0,
'group' => 'Menu',
'position' => 100
));
$installer->endSetup();
