Your recipe should work, assuming the file was added in r100 and never changed or copied afterwards. You may pass --deltas to 'svnadmin dump' (no reason not to). It'll offset r101:r200 revnums by one in the new repository.
Another way is to use svnsync with path-based authz blocking the file (and all its copied) from the sync user. Giorgio F.
