I've been trying to simulate ISR in CSS of Timer0 and find that TIF 
bit is set but PIEIFR bit is NOT SET.

after manually setting PIEIFR bit the the Vector address is NOT taken 
from PIE vector table but from Vector table in Bootrom even though 
ENPIE (enable PIE bit) is set.

could someone guide me?

not sure if you are already using the tidcs examples
  example in tidcs - ti document sprc097 gives example of using timer 0 ISR
  instead of changing the address in PIE, it creates a new ISR function within main program and
maps the interrupt adress to it
  try to start from the examples and modify the code from there
