In the hunt for another key wicket, South Africa bowled out Kapp early and the pacer finished with outstanding figures of 1/16 in four overs.
Having survived the early burst of pace, Sciver-Brunt and Heather Knight led the England fightback with a 133-run stand for the third wickets, which is the highest partnership in knockouts in the tournament.
Sciver-Brunt showed no signs of the calf injury that had kept her out the last three matches as she dazzled with her footwork and ran hard between the wickets.
The English captain struck 11 fours and a six, en route her eighth half-century in Women's T20 World Cup.
It drew her level with the game's greats Suzie Bates (New Zealand) and Beth Mooney (Australia).
