My theory: 1. Sektor was damaging FrankCrank as he ran into the water. +1 2. Sektor was electrocuting FrankCrank. There might be a fluke moment where that begins at the same moment FrankCrank fell into water. Electrocution fries the player for a while before registering the frag, so +1 delayed frag. 3. Mortally wounding a player and finishing them off in water gives a bonus frag. +1 bonus frag. Several things beginning at same the moment for 1-in-a-million triple frag!
