You would add the code to the more_share_options template.

Put it between or after any of the existing blocks... each block start and ends with a comment such as:

<!-- Google+1 END -->
<!-- StumbleUpon START -->

Put all of your code between <td> </td> tags, so...

<td>
<style type="text/css">
@import url(http://www.google.com/cse/api/branding.css);
</style>
<div class="cse-branding-right" style="background-color:#FFFFFF;color:#000000">
  <div class="cse-branding-form">
    <form action="http://www.yourdomain.com" id="cse-search-box">
      <div>
        <input type="hidden" name="cx" value="partner-pub-4437065443706544370654437065" />
        <input type="hidden" name="cof" value="FORID:9" />
        <input type="hidden" name="ie" value="ISO-8859-1" />
        <input type="text" name="q" size="45" />
        <input type="submit" name="sa" value="Search" />
      </div>
    </form>
  </div>
  <div class="cse-branding-logo">
    <img src="http://www.google.com/images/poweredby_transparent/poweredby_FFFFFF.gif" alt="Google" />
  </div>
  <div class="cse-branding-text">
    Custom Search
  </div>
</div>
</td>

You may need to manually enter a width or alignment setting for the <td> tag.
