It looks to me as if a second round of evaluation is being done.
During the first round the "\"s would be removed leaving "[[0-9]+]".
The second round would pair the first "[" with the first "]", the
one before the "+" and would make your character class be digits
or opening square bracket. The final square bracket would be literal.
You may have to play with the number of backslashes, probably doubling
them though in some troff documents it was even necessary to tripling
them in order to have one preserved when it was needed.
