Demi Stokes also chipped in with two assists as the Lionesses clinched their second high-scoring victory over the White Eagles in three days.
Ellen White and Gemma Davison (2) were also on the scoresheet, and Nevena Damjanovic put through her own net in Stara Pazova.
Saturday’s 7-0 triumph ensured a win for Mark Sampson’s side would put England top of the group, securing at least a runners-up spot for next year’s finals.
It didn’t take long for the visitors to break the deadlock, when Scott headed home Stokes’ fine delivery on 13 minutes.

White then hooked in from close range, before Davison rounded the ‘keeper and converted to earn a 3-0 half-time lead.
A minute after the restart, the Chelsea winger doubled her personal tally, slamming another Stokes cross into the back of the net.
The ball then deflected in off Damjanovic from Davison’s rebound, and Parris netted her first for the Lionesses’ senior squad, heading in Karen Carney’s cross.
