I actually have my own function for this that handles either the text  
or numeric values for true used in other environments:

Function GetBoolVal(value As Variant) As Boolean

   If value.Type = Variant.TypeInteger Then
     If value = 1 Then
       Return True
     Else
       // anything not 1 is false in our world
       Return False
     End If
   ElseIf value.Type = Variant.TypeString Then
     If value = "true" or value = "1" Then
       Return True
     Else
       // anything not "true" or "1" is false in our world
       Return False
     End If
   ElseIf value.Type = Variant.TypeBoolean Then
     Return value
   End If
   // Just for safety sake
   Return False

End Function

It works great for the work I do calling external shell tools where I  
deal with returns of both the words and the values.
