Leaving aside question of Org, 

,---- from package.el
|    ;; Prefer Package-Version; if defined, the package author
|    ;; probably wants us to use it.  Otherwise try Version.
|    (pkg-version
|     (or (package-strip-rcs-id (lm-header "package-version"))
| 	(package-strip-rcs-id (lm-header "version"))))
`----

,---- from package.el
|       (unless pkg-version
| 	(error
| 	 "Package lacks a \"Version\" or \"Package-Version\" header"))
`----

I think the policy differs based on what elisp file is being
considered....

The above data point is inconsequential for non-core Org because it is a
multi-file package and it's version comes from `org-pkg.el' bundled
within the tar.
