Specularity/reflection are properties specified in the finish{} block. Since
you can't have a finish map in the official version of POV-Ray, you have to
use a texture_map. So you might want to predefine your pigment and use it in
each entry of the texture_map:

#declare thepigment = pigment {...}
texture {
    tga "finishmap.tga"
    texture_map {
        [0 pigment{thepigment} finish{specular 0}]
        [0 pigment{thepigment} finish{specular 1}]
    }
}
