Run TC 9.20 scripts on TC 14.10

I have finally succeed to isolate the function where the error came from. The problem is in using a CASE with the result as numerical interval (e.g. 12..25 in DelphiScript). TC 9.20 does recognize this syntax, but last TC release doesn't.
In other words, the below function using DelphiScript syntax, won't work within last TC release, but will do within TC 9.20 and perhaps within other releases in between.

function CaseExemple: OleVariant;
var i:integer;
begin
 for i:=0 to 200 do begin
  case i of
        0..100:
             begin
              if i=50 then Log.Message('This figure, '+IntToStr(i)+ ', is within 0-100 interval');
             end;
        101..200:
             begin
              if i=150 then Log.Message('This figure, '+IntToStr(i)+ ', is within 101-200 interval');
              end;
           else begin

             end;
  end; //of case
 end; //of for
end;
