Photoshop can read it with any tag type, but writes as type long for compatibility with some unspecified application (and the comment has been in there a long time).
Does Photoshop compensate for long-swapped corrupted data(*)? If it does, what is its criterium? What course of action do you recommend?
We don't byte swap the IPTC data block.
The data in that block is treated separately from the TIFF containing it.
