I don't think there was any way to format numeric labels in version 5.x 
and older.

However, MapServer 6.0 (RFC 64) introduced a toString() function that 
can be used in labels as follows:

       TEXT ("[area]")

       TEXT (tostring([area],"%.2f"))

       TEXT ("Area is: " + tostring([area],"%.2f"))
