How can I set attribute option's position when I create it by program?

Question

I found this article to add new options for a attribute using program perfectly:
http://www.danneh.org/2011/01/getting-value-of-attribute-option-and-adding-a-new-attribute-option-in-magento/

But every attributes will always create with position '0' and I want to sort them because their values are numbers.
Can I set attribute options' position when I create them or update the position after I create them?

Answer 1

Try:

public function addAttributeOption($attributeCode, $optionValue, $sortPosition) {
    $attribute = Mage::getModel('eav/entity_attribute')->loadByCode('catalog_product', $attributeCode);      
    $option = array('value' => array($optionValue, $optionValue), // set default value, store value
                    'order' => array($sortPosition)); // set sort posiiton
    $attribute->setOption($option);
    $attribute->save();

    return $this->getAttributeOptionValue($attributeCode, $optionValue);
}
