He is right. We tried the same.
No matter what x/y arguments are given in

TPostScript mps("fff.ps");
mps.Range(x,y);

the PS picture has always the same size.

In the TPostScript::Range source one can find

if( fType != -113) { xps = fXsize; yps = fYsize; }
else { xps = xsize; yps = ysize; }

Thus only in the case fType = -113 (EPS) the scaling
shouldn't be allowed (correctly).
But even if the fType is set explicitely to e.g.

TPostScript mps("fff.ps", -111);

the effect is just the same.

I think the reason is that the

28 20 t .25 .25 scale gsave

is written into the postscript file in the moment when using
the constructor - and remains unchanged by the Range() call.
