                  'option_type_id'=> -1,
         ),
         array(
                  'is_delete'     => 0,
                  'title'         => 'Extra Large',
                  'price_type'    => 'Fixed',
                  'price'         => '100.0',
                  'sku'           => '1',
                  'option_type_id'=> -1,
         )
    )
);

$product->setCanSaveCustomOptions(1);
$product->save();

I've Given 5 Steps to to insert product custom option in magneto. Also check option data fields link below:

Step 1: Set Admin Store

Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);

$product = Mage::getModel('catalog/product')->load($productID);

Step 3: Create Custom Option Data Array

$optionData = array(
            'title' => $product->getName(),
            'type' => 'radio',
            'is_required' => 1,
            'sort_order' => 0,
            'values' => array(
                array(
                    'title' => 'Standard',
                    'price' => $standardPrice, // $standardPrice value like 10.11 OR '10.11'
                    'price_type' => 'fixed',
                    'sku' => '',
                    'sort_order' => 0,
                ),
                array(
                    'title' => 'Premium',
                    'price' => $premiumPrice,
                    'price_type' => 'fixed',
                    'sku' => '',
                    'sort_order' => 0,
                ),
                array(
                    'title' => 'Deluxe',
                    'price' => $deluxePrice,
                    'price_type' => 'fixed',
                    'sku' => '',
                    'sort_order' => 0,
                )
            )
        );

Step 4: Set Product Option Data

$product->setProductOptions(array($optionData));
