Magento : Custom extension overwrites gender values. How to Fix?

Question

Shop owner called telling me the gender select in the store contains Apple and Banana instead of male and female. Turns our this was the case in all form frondend/backend.

After some digging I found an extension with an mysql4-upgrade file. The only place I got any Apples, so this must be causing this problem:

$installer->addAttribute('catalog_product', 'p_layout', array(
             'label'             => 'Motiv',
             'type'              => 'varchar',
             'input'             => 'select',
             'backend'           => 'eav/entity_attribute_backend_array',
             'frontend'          => '',
             'source'            => '',
             'global'            => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_GLOBAL,
             'visible'           => true,
             'required'          => true,
             'user_defined'      => true,
             'searchable'        => false,
             'filterable'        => false,
             'comparable'        => false,
             'option'            => array (
                                            'value' => array(
                                                '1' => array('Apple'),
                                                '2' => array('Banana'),
                                            )
                                        ),
             'visible_on_front'  => false,
             'visible_in_advanced_search' => false,
             'unique'            => false
));

$attributeId = $installer->getAttributeId('catalog_product', 'p_layout');


if ($attributeId) {
    $option['attribute_id'] = $attributeId; //p_layout
    $option['value']['optionone'][0] = 'Apple';
    $option['value']['optionone'][1] = 'Apple';
    $option['value']['optionone'][2] = 'Apple';
    $option['value']['optionone'][3] = 'Apple';
    $option['value']['optiontwo'][0] = 'Banana';
    $option['value']['optiontwo'][1] = 'Banana';
    $option['value']['optiontwo'][2] = 'Banana';
    $option['value']['optiontwo'][3] = 'Banana';

    $installer->addAttributeOption($option);
    $installer->addAttributeSet('catalog_product', 'Stuff');

In eav_attribute_option_value I found option_id 1 and 2 being Apple and Banana. I guess during an update or the recent page move to another server this was overwritten.

Any idea how to fix this? I would like to avoid having this mess again...

Looks to pretty much like this: Upgrade script - Create new select attribute with options

Could the missing 'source' => 'eav/entity_attribute_source_table' causing this problem?

Or is '1' => array('Apple') the problem? I noticed in other places they set the value like this: array('Apple', 'Banana')
