<Artwork> is available from the field selector in virtual tags creator.
Should the value returned ever be anything besides "Unknown Artwork" ?
Maybe something like "Cover", "folder", "Embedded" or "Linked" ?

Could the <Artwork> field in virtual tags be enabled to provide feedback on the MIME type of artwork, please?
A quick google of the bass library API says it can return the apic code for the picture type and even "-->" for the MIME type to show its a link rather than embedded artwork.
