In the last two pages of the rulebook there is a clarifications section. In regard your question it says:
2. Scoring cards and placing them on the Finished! Pile:
When using actions which place or move cards in your Present Area, you should immediately score these cards the moment they are score-able.
You interrupt the action, place that card on the Finished! Pile and immediately draw a replacement card (which you may score again and so on), before continuing with the action.
This is in effect for all cards, which you draw in Step 3 and Step 4, and for all cards, which you draw or move to the Present Area by using the actions “Cards into the Past”, “Cards from the Past”, “1 Card into the Future”, “All Cards into the Future” and “Exchange Cards”.
So, in your example you should score the card 8.
