You could just put in a MultiVal instead, it does more or less the same thing:

xml code:

---

<MultiVal Name="FormatBarAlign">
    <DispLabel>MultiVal</DispLabel>
    <DispHelp>Description/DispHelp>
    <Values>
        <Value DispLabel="Option 1">option1</Value>
        <Value DispLabel="Option 2">option2</Value>
    </Values>
    <Default>option1</Default>
</MultiVal>

---

EDIT: It's a ComboBox control, not a radio button, but meh.
