It is theoretically possible but not likely.
Teej do not believe other peoples crap do your own research man. (and you two naughty boys cfh & DD) .
The “direct result” is only 1 part of 5 steps that need to be gone throught to rank the pool in the event of a draw.
From the RWC site rules page http://www.rugbyworldcup.com/home/tournamentrules/index.html
If you read the page or the quote below you will see that the pool rankings are determined by steps 1-5 below (see bold bit) .
If scotland beat us by 8 then ok they go up one rank because they won, but then we go up because of points diff, tries diff, points tally and tries tally.
So unless scotland can put 81 points on us, and 15 tries even with a pool pts draw, we still go through. Or then they have to go up by 4 ranks as they are currently 8th and we are 4th. IRB rankings
Rankings at the completion of the pool phase
At the completion of the pool phase, the teams in a pool are ranked one through five based on their cumulative match points, and identified respectively as winner, runner-up, third, fourth and fifth.
If at the completion of the pool phase two or more teams are level on match points, then the following criteria shall be used in the following order until one of the Teams can be determined as the higher ranked:
The winner of the match in which the two tied teams have played each other shall be the higher ranked;
The team which has the best difference between points scored for and points scored against in all its pool matches shall be the higher ranked;
The team which has the best difference between tries scored for and tries scored against in all its pool matches shall be the higher ranked;
The team which has scored most points in all its pool matches shall be the higher ranked;
The team which has scored most tries in all its pool matches shall be the higher ranked;
Should the tie be unresolved at the conclusion of steps 1 through 5, the team that is higher ranked in the updated Official IRB World Rankings on October 3, 2011.
