It doesn’t resolve, because your url pattern actually hard-codes the order value (it will always be ‘0’).
You have to provide a way to change the order value from within the URL itself.
To be precise:
urls.py
url(r'^review/$', 'checkout.views.review', {'order':'0'}, name="order-review-default-fallback"),
url(r'^review/(?P<order>[\d]+)/$', 'checkout.views.review', {}, name="order-review"),
should solve your problem.
