Hi Utkarsh, Changing DataRep.ScalarOpacityUnitDistance shows up as what's in the Scale input box. Going the other direction, setting the Scale in the GUI is what python prints for DataRep.ScalarOpacityUnitDistance so they do seem to be the same thing?

Mark, Scale on the ColorScaleEditor is control the scale used to map data scalars to colors or opacity, while sampling distance controls the length at which the samples are accumulated when volume rendering. The two are indeed different.
