ORDER BY variable undefined

[area]

As with my other bug report, this query works correctly on both 2.1.5 and 2.2.0:

MATCH (p:Person) with p, rand() as rng return p, rng

but this one only works on 2.1.5:

MATCH (p:Person) with p, rand() as rng return p ORDER BY rng

and on 2.2.0 gives the error:

rng not defined (line 1, column 58 (offset: 57))
"MATCH (p:Person) with p, rand() as rng return p ORDER BY rng"

Thanks for the report! I've confirmed the issue and will pass it along to our team.

Further to this, the following command works:

MATCH (p:Person) with p, rand() as rng return p, rng order by rng
