Because Scotland's group only has 5 teams, the points total of all the other second place finishers will not include matches against the teams that finished 6th in their group, so almost certainly you will have to deduct 6 points from all the teams totals.
For a team like the Republic of Ireland, they would benfit from Montenegro finishing bottom as they only drew with them so would have less points deducted than if Georgia finish bottom who they have beaten twice - make sense

Personally i think that Iceland should be ok
