Package ordering is done solely through Requires: and PreReq:. Obsoletes:
is just a variant of -U where the package to be removed is added to the
transaction set immediately after the package to be installed.

So, the answer is no. Well, there's always
	rpm -U --nodeps C B A
which will install C B A in exactly the order given on the command line.

No way at all, nor is "good" meaningful here IMHO.

Try duplicating the file creation in %post of both packages to remove the
implicit ordering requirement, 1st package installed creates the file,
other packages just use.
