Here the typesetter for the 1906 LDS edition added a plural s to the word judgment. This plural form was not extended to any subsequent LDS edition since the 1906 edition never served as a copytext. Either number will work here in 3 Nephi 27:27. There are two other instances of “according to the judgment(s)” in the text, one in the singular, the other in the plural:
(For the evidence against revising the second case to the singular, as “according to his judgment which is just”, see the discussion under Omni 1:22.) For each case of this phrase, the critical text will follow the earliest text, thus the singular “according to the judgment which I shall give unto you” here in 3 Nephi 27:27.
Summary: Maintain the singular judgment in 3 Nephi 27:27, the reading of the earliest textual sources (𝓟 and the 1830 edition).
