How to order by sum in each rollup data group? - postgresql-9.5

Question

I have my animal table with points for each animal, its color and name.
create table animals (
category text,
color text,
name text,
points numeric
)
insert into animals values ('CATS', 'WHITE', 'FLUFFY', 1234)
insert into animals values ('CATS', 'WHITE', 'FLUFFY', 2568)
insert into animals values ('CATS', 'WHITE', 'SALLY', 124)
insert into animals values ('CATS', 'WHITE', 'SALLY', 12401)
insert into animals values ('CATS', 'WHITE', 'MR KITTY', 101)
insert into animals values ('CATS', 'WHITE', 'MR KITTY', 1761)
insert into animals values ('CATS', 'BLACK', 'DARTH CATHER', 1761)
insert into animals values ('CATS', 'BLACK', 'DARTH CATHER', 2361)
insert into animals values ('CATS', 'BLACK', 'ITS A TRAP', 171)
insert into animals values ('CATS', 'BLACK', 'HAN SOLO', 1713)
insert into animals values ('DOGS', 'BROWN', 'PLUTO', 1761)
insert into animals values ('DOGS', 'BROWN', 'DUFFY', 23611)
insert into animals values ('DOGS', 'BROWN', 'PICACHOU', 1171)
insert into animals values ('DOGS', 'BROWN', 'DUFFY', 17123)
insert into animals values ('DOGS', 'BLACK', 'MICKEY', 17361)
insert into animals values ('DOGS', 'BLACK', 'JACKSON', 23361)
insert into animals values ('DOGS', 'BLACK', 'BA', 1751)
insert into animals values ('DOGS', 'BLACK', 'MACGUYVER', 17513)
insert into animals values ('FISH', 'YELLOW', 'LENON', 1571)
insert into animals values ('FISH', 'YELLOW', 'BEUSCONI', 17153)
I need to return sql output similar to output from Excel pivot table:
(with proper descending order by sum of points within data groups)
I'm really close with this query:
with data_grouped as
(
Select
COALESCE ( category, 'Total'::text) as category,
COALESCE ( color, 'Total'::text) as color,
COALESCE ( name,'Total'::text) as name,
sum(points) as points
FROM animals
GROUP BY category, color, name
),
data_evolutions as
(
select grouping(d.category, d.color, d.name) as GR_ALL,
d.category,
d.color,
d.name,
sum(d.points) as points
from data_grouped d
group by rollup(d.category, d.color, d.name)
order by category, color, name
)
select
COALESCE (d.category, 'Total'::text) as "CATEGORY",
COALESCE (d.color, 'Total'::text) as "COLOR",
COALESCE (d.name, 'Total'::text) as "NAME",
points
from data_evolutions d
order by
CASE WHEN category IS NULL THEN 1 ELSE 0 END, category,
CASE WHEN color IS NULL THEN 1 ELSE 0 END, color,
CASE WHEN name IS NULL THEN 1 ELSE 0 END, points desc
but still I get wrong order.
Animals are ordered by name, not by sum.
How should I change my query to get descending order by sum of points within each level?
I need correct sums, and order with totals and subtotals.
