/**
* ### Available since 1.2.0.
* ### ZSCORE key member
* Returns the score of member in the sorted set at key.
*
* If member does not exist in the sorted set, or key does not exist, nil is returned.
* ### Return value
* Bulk string reply: the score of member (a double precision floating point number),
* represented as string.
* ### Examples
* ```
* redis> ZADD myzset 1 "one"
* (integer) 1
* redis> ZSCORE myzset "one"
* "1"
* redis>
* ```
