Confused with the container value of Field Order

Anyone can explain what numbers should I use for TFF and BFF ?

It uses the same super confusing syntax that MOV/MP4 uses, and barely anyone properly understands or uses correctly. Its one of those cases were borrowing the spec from MP4 was probably not a good idea.
In the most generic case I would argue that fields are often stored in the correct order (top first), or even as one frame, and only the display order changes, so you would use 1 = TFF and 9 = BFF.

Most newer advanced video codecs will store the field order in the codec headers themself though, and this field is likely ignored by the majority of players.
