Hi Upendra, The reason the "reporting scale" is attached to this name is that the fundamental measurement, or property, to which it refers produces numbers that are not comparable to pH derived using other techniques. (They are actually measuring different quantities, not just a different offset/scale value.)
From what I (not a scientist!) understand, it is often the case that pH that doesn't mention its scale has been measured in a way that is not an effective indicator of pH in sea water. So it is very important to understand the way the pH was measured, in order that the values be reported compatibly with others. I am not knowledgeable enough to know the right answer to your two questions, but the above may be useful input.
