Whether a special passport is considered Official or not does not matter here. The text you quoted clearly mentions that both passports must be of the same type, and yours arenβt. So the visa is no longer Valid.
Special passport is unique to Turkey. It is given to government officials for their personal trips, so it is not a service passport in any sense
Just for the record, a Service passport would have been fine too. Both of the passports need to be from the same country and of the same type.
Interestingly Timatic does not mention that the passports need to be of the same type.
A passenger may enter the USA with a valid visa in an expired passport, if also holding a valid passport of the same nationality. Transfer of a valid visa to a valid passport is highly recommended in all cases.
However, I would weigh US State Department's statement more than that of Timatic. The description on State department's website is crystal clear:
Both passports (the valid and the expired one with the visa) should be from the same country and type (Example: both Uruguayan regular passports, both official passports, etc.).
