If a track is ineligible then the only way or getting it on your phone currently is to change its media type to a podcast or an audiobook, which can be synced.
I note you say there is nothing strange about the tracks. If that is the case then maybe it will be possible to get thm no the cloud. Have you read the requirements for match to work with a track. If these tracks see to meet those requirements then maybe you should try re-ripping them and trying again. There may be soe problem with the rips.
