How can I use <source_model> for a textbox in Magento for system.xml?
===

Because it's for a textbox, I'm not sure how the array is supposed to work.

**This fails.**

    public function getDefault_dailymatches()
    {
        return array(
          array('value' => 0, 'label' => Mage::helper()->__('First item')),
          array('value' => 1, 'label' => Mage::helper()->__('Second item')),
          array('value' => 2, 'label' => Mage::helper()->__('third item')),
         // and so on...
        );    
    }


**This also fails.**

    public function getDefault_maxmatchvotes()
    {
        $default = 100;
        return $default;
    }
