isort produces inconsistent order with capitalization

[rouge8]

Given:

from sqlalchemy.dialects.postgresql import ARRAY
from sqlalchemy.dialects.postgresql import array

Different values of PYTHONHASHSEED produce different results:

$ PYTHONHASHSEED=2856684698 isort --diff --force-single-line --force-sort-within-sections --dont-order-by-type t.py
