title: Magento 1.7.0.1 resets price to 0 when using custom options
body: <p>I'm using <code>Magento 1.7.0.1</code> just recently upgraded from <code>1.6.2.0</code>. I have the SCP extension as well as MageWorx Advanced Custom Options.</p>
  
  <p>I have a configurable product where the simple products that are associated have custom options.</p>
  
  <p>If you select the drop-downs in the following combination you will see the multi-select popup with the custom options available. Just before the custom options box pops up it will switch from £99.99 (correct) to £0.00. Oddly, if you click a custom option then click "Add to Cart" it recognises this and adds it to cart with the custom option and the correct pricing!</p>
  
  <p>The combination is as follows:</p>
  
  <ol>
  <li>A6</li>
  <li>5000</li>
  <li>300gsm Gloss</li>
  <li>24hrs</li>
  </ol>
  
  <p>You will see it briefly switch to £99.99 then revert to £0.00. This is where the problem lies. If anyone can provide some assistance that would be great. I've tried the obvious fixes such as editing the price += float in options.phtml (doesn't exist anyway!) and ensuring I have an options.phtml in my theme folder. I've also modified the price_clone as that has also been reported to fix this, but doesn't in my circumstance.</p>
  
  <p>Many thanks</p>
