I'm also having a similar issue with the same question that has been brought up by the OP.
For context, I am currently using a character with this archetype in a new campaign, with a flame doshko. The character is almost level 3.
From what I understand, the 'Tooth that Seeks Honor' ability kinda stunts itself. Looking at the ability, the main problem that comes with it is the "until the ***START*** of your next turn."
Not the end, the start. What this implies to me, is, the only way that you are ever able to make use of the special weapon properties (disarm/sunder/trip- the ones that require a standard action to use) that you may/may not obtain from missing is if you delay/hold your action when your turn comes around. If you do delay/hold action before using your standard action, you CAN get your AoO back before your turn comes back to you, but you won't get another one until next turn... oh, and your initiative placement is now far worse.
So, with that all said and done, it CAN be helpful for your teammates to put your opponent in an unfortunate situation. Your character has done their part, been EXTREMELY tactical and predicted enemy movements/actions/whatever, and has received a reward on their turn, as a result. All this said, however, it feels as though all of these abilities, when laid out, seem as though they'd function more fluidly if they lasted until the END of the character's next turn.
If they lasted until the end, your character could full attack, perhaps miss twice, then now have the reach and the neat fun of a combat maneuver bonus- it wouldn't do MUCH, but it would change up the battlefield without causing am initiative headache AND your character could still hold on to their precious AoO.
Now, perhaps this may imply that an errata may be due in place because of faulty word choice, but all of this if and only if you choose to use a doshko that ISN'T unwieldy- which a lot of them are.
TL,DR; Unless your doshko is unwieldy (in which, this won't apply to you), the 'Tooth that Seeks Honor' ability requires a lot of prediction and sacrifice from the character with this archetype. It seems like it may need an errata/clarification to give the ability a duration til the end of your next turn.
