I have the following data in umbraco.conf

      <glossary>
        <items>
          <item>
            <data alias="term">Term1</data>
            <data alias="defind">Def1</data>
          </item>
          <item>
            <data alias="term">Term2</data>
            <data alias="defind">Def2</data>
          </item>
          <item>
            <data alias="term">Term3</data>
            <data alias="defind">Def3</data>
          </item>
        </items>
      </glossary>

and I have the following razor macro that currently works.

<umbraco:Macro runat="server" language="cshtml">
@foreach(var item in Model.glossary )
  {
  <h3>@item.data[0].InnerText</h3>
  <p>@item.data[1].InnerText</p>
  }
</umbraco:Macro>

I want to sort on the text of the data[0] and I tried a bunch of things, but I guess I not undersanding the OrderBy Clause

<umbraco:Macro runat="server" language="cshtml">
@foreach(var item in Model.glossary.OrderBy("item.data[0].InnerText") )
  {
  <h3>@item.data[0].InnerText</h3>
  <p>@item.data[1].InnerText</p>
  }
</umbraco:Macro>

Any help here?
