When the player was killed using triggeraction the attacking player doesn't get the kill and doesn't lose AP, nor does his spar rating change.
As long as the action... events aren't mixed with other events the script engine could check whether the playerhearts are zero after this event. If they are - do the same you do when getting killed with hitobjects/sword/bombs/whatever.
Do not say "use a string to save the kills and script it yourself". The kills mustn't vanish when the account was reset.
