In the scene below are two spheres with white dots. I expected both the
textures to be the same, except for the red dot. But it seems that scaling
the not only affects the pattern_type but also the texture map. I had a quick
look in the docs but found nothing that explains.
Is this the to be expected behaviour, or...
How can I get the result I want? Layerd textures won't work because of the
different finishes.

I think this is what the reset_children patch in UVPov is for. It allows
you to transform the top level of a texture, leaving it's component
parts(it's children) unchanged.
Other than using that patch, I think this will do what you
want(untested!):
#declare TestT2= texture {
cylindrical
scale <2,1,1>
texture_map {
[0.7, TestT scale < 0.5, 1, 1>]//scale this part to compensate
[0.8, pigment {red 1} finish {phong 1}]
}
}

The warp{reset_children} is perfect, as it also works for turbulence witch
your second solution does not.
Thanks Chris,
