Mode changes are ignored, unless the --bypass option is used.
Quoting 'hg help import':

    Use --bypass to apply and commit patches directly to the repository, not
    touching the working directory. Without --exact, patches will be applied
    on top of the working directory parent revision.

Adding a test step execising --bypass would actually be a nice addition for
test-import (TODO for someone with a later patch).
