You have a couple options:
<component jsfid="outputScore" extends="outputText">
<converter jsfid="convertNumber">
<attributes>
<set name="maxFractionDigits" value="1" />
</attributes>
</converter>
</component>
or:
<component jsfid="outputScore" extends="outputText">
<attributes>
<set name="converter" value="javax.faces.Number" />
</attributes>
</component>
But, I missed many of the base converter's. The defaults are defined in the
/META-INF/clay-config.xml file in the clay archive.
If you find some missing from the JSF spec., please post your definition in a
bugzilla ticket and I'll add it to the base clay config (javax.faces.Number is
missing)

The converter component definition is correct and this one is missing from the
base clay config file. If you want to apply this converter to a component, you
need to nest it under the component as a "converter" node or provide the
componentType (registered name of the converter) as a converter attribute of
the target component (see example above).
