I think you need to focus on the request to define a history of item prices. I wouldn't go into triggers to do this but actually do it via code. You have a history of an item's price over time via your Orders detail currently. Just query that table for the minimum date for that item & price. Poof, the request is done when slammed into a table for reporting. Now in your item form, you write a new record to this new table for a price change event.
Triggers are great as well as a bitch. Finding that data is being moved via a trigger is difficult when you think it is going to be done by a sproc. Just saying I have been bitten by this.
