Lets begin with the Synopsis of the "Penalty Try"
Section 6.
Penalty try
(d) the Referee may award a penalty try if, in his
opinion, a try would have been scored but for the
unfair play of the defending team. A penalty try is
awarded between the goal posts irrespective of
where the offence occurred.

When awarding a penalty try, the referee has to be 100% sure that if the infringement did not occur a try would have been scored.
The referee does not have to be 100% sure, the law states,
"in his opinion"
Unfair play can be described as tripping to tackling a player without possession of the ball and even high tackles. A few seasons ago, stealing possession of the ball with more than one defender in the tackle could constitute a penalty try but the laws were amended to award stealing possession a penalty only. (When I find a newer link of the 2006 ARL Laws, I'll let you know where the amendments are)
Lets move to the "Eight Point Try" section.
Section 13
Offence against Try scorer
9. If a player fouls an opponent who is touching down
for a try, a penalty kick at goal shall be taken from in
front of the goal posts after the attempt to convert
the try. After his kick has been taken the ball shall be
deemed dead and play shall be restarted from the
halfway line. This law applies to the period during
which the ball is touched down for a try and not to
any subsequent period.
In short, a penalty kick at goal from in front is given after the initial attempt of conversion for the try.
This is the important part of the law...
This law applies to the period during
which the ball is touched down for a try and not to
any subsequent period.
adj. subsequent ref. Wiktionary
1. Following in time; coming or being after something else at any time, indefinitely.
2. Following in order of place; succeeding.
So when a player is touching down to score a try and an opponent knees the try scorer in the back or stomps on his head during the touch down, the Offense against the Try Scorer law comes into act. If for instance after the try scorer has finished grounding the ball and is
subsequently fouled, this law does not come into play.
Oh, and one more thing....

I challenge you to find any reference in the rule book where it calls it an '8 point try.'
Section 17. REFEREE'S SIGNALS
Law 3. Eight Point Try. This term is used to indicate that a
penalty kick has been awarded for foul play against a try
scorer. Instruct a Touch Judge to take up position in front
of the posts ten metres from the goal line before retiring
behind the goal posts to judge on the conversion attempt.
