Increments the score of member in the sorted set stored at key by
increment.
If member does not exist in the sorted set, it is added with increment as
its score (as if its previous score was 0.0).
If key does not exist, a new sorted set with the specified member as its
sole member is created.
An error is returned when key exists but does not hold a sorted set.
The score value should be the string representation of a numeric value, and
accepts double precision floating point numbers.
It is possible to provide a negative value to decrement the score.
