well , one way is to create your MouldedLook texture and Cracks texture
separatley ..

Then use an average statement by pounding your texture .. this is done like
that

Texture {average
        texture_map {
            [weight_texture1   MouldedLook]
            [weight_texture2    Cracks]
    }
}
