Simultaneous Touch of Oblivion and aggravated damage

If a vampire is affected by Touch of Oblivion at OBL and aggravated damage simultaneously, which effect is handled first?

In case Touch of Oblivion is handled first, the vampire would be considered wounded, and could by burned by aggravated damage.

In case the aggravated damage is handled first, the vampire would be wounded and going to torpor, but then Touch of Oblivion woudn't affect him, because he is already in her way to torpor.

Rulebook states that normal damage is handled first, then aggravated damage. But I can't find anything about these torpor effects (Entombment, Coma, Touch of Oblivion).

Combat
Touch of Oblivion
Oblivion Strike: put this card on the opposing minion with 2 counters. The attached minion burns 1 counter from this card instead of unlocking as normal. If this card has no counters, burn it.
Superior Oblivion Strike: send the opposing vampire to torpor or burn the opposing ally.

I think that would depend on what the exact source is for that aggravated damage... would you have an example?

In combat, the usuals order of things would be:

Combat Sequence

Combat occurs in a series of one or more rounds. Each round of combat has seven steps:

1. Before Range: Play cards before range is chosen.
2. Determine Range: Use maneuvers to change the range to close or long.
3. Before Strikes: Play cards before strikes are chosen.
4. Strike: Announce and resolve strikes.
5. Damage Resolution: Prevent and mend damage.
6. Press: Use presses to continue into another round or to end combat.
7. End of Round: End of round cards and effects are played here.

This usually means that the Touch of Oblivion resolves first, in step 4.
Damage handling - including aggravated damage - only happens later in combat, in step 5.

The most common case where this could happen would be "deal damage durign the normal strike resolution phase" under an effect like Dawn Operation.

In the case of Aggravated damage being inflicted at the same time as "touch of oblivion" is resolved, the vampire goes to torpor before dmage is appled, becase all damage dealt opens a "damage resolution" window, where damage can be prevented or must be mended.

so tl;dr:
If a vampire is inflicted with aggravated damage at the same time as touch of oblivion resolves, they go to torpor first.
