If I have a Candlelit Sanctum and I am at 7 points for the eight point, I draw for the point, but could I order the Sanctum and then draw?

No, you cannot order the Candlelit Sanctum trigger to resolve before drawing the card for your 8th point.

According to RiftJudge FAQ #8212 and RiftJudge FAQ #1422, the scoring process (or the draw that occurs at 8 points instead of gaining a point) must be completed before any "on-conquer" triggers are placed on the chain.

Here is the required sequence:

1. Conquest occurs: You move a unit to the battlefield and meet the criteria for a Conquer.
2. Scoring process: Because you are at 7 points and attempting to gain your 8th point, the rules for Scoring trigger. Since you are at the victory threshold, the game instructs you to draw a card instead of gaining a point. This must be completed first.
3. Trigger placement: Only after that scoring/draw process is complete are the "on-conquer" triggered abilities (like that of the Candlelit Sanctum) placed on the chain.
4. Resolution: The Candlelit Sanctum's ability then resolves as a chain item.

In short, the scoring/draw is a prerequisite for the conquer to be considered "completed," so the battlefield's trigger cannot occur until that action has resolved.
