Less-than / Greater-than Comparisons in Homomorphic Encryption

It seems to be impossible to find a working solution for less-than / greater-than comparison for holomorphic encryption using Microsoft SEAL library, and the library does not seem to provide such functionality. The research papers provide only theoretical approaches without sample codes.

Is there a working example exists anywhere using SEAL library that compares two ciphertexts? that is, produces something as simple as Enc(x1) < Enc(x2) ? true : false.

Related issues on the SEAL library page: #162, #397.
