Using a BOM (TOM?) to communicate endianness

How do we distinguish between little-endian and big-endian trits?

For example, consider the following sequence of trits:

00++000++--+-_bal3

If we interpret this value as little-endian (least significant trit first), then the value is -424242₁₀.
If we interpret this value as big-endian (most significant trit first), then the value is 79022₁₀.

We have the same problem with bits, of course, which is (for example) why some UTFs use a BOM.

Should decoded trits have a similar feature (Trit Order Mark — TOM)?
