I do not understand why you are trying to access directly the underlying
tdb. This sounds completely wrong for various reasons, including the
fact it breaks the ldb abstraction (we could decide to move and use a
different backend, for example ntdb or something else in future).
But I also do not see why you need that at all.
Why can't you simply lookup an LDB entry to save/read out the current
schema version ?

Simo.
