xmin::bigint doesn't work because that implicit CAST doesn't exist. If needed, I'd use xmin::text::bigint; that should work.

Ok, so it took a lot of googling to figure this one out, but you can do it with something like so.
So the manual says there is no way for a statement-level trigger to examine the row(s) modified by the statement.
Is there any way to get the xmin or cmin of the transaction that fired the trigger? Or can I look up the last xid for a table some where?
SELECT *
FROM strand_scores
WHERE xmin::text = txid_current()::text
It appears you can't convert a xid type to int or bigint, not sure why. I guess I should leave a comment on the manual page.
