You could create a UserTag that opens a pipe to your script, passes
whatever arguments the script requires and collects/returns the output
for your use.

If you call the UserTag from your etc/log_transaction file, you could
save the results into a scratch.  From there you could save the
scratch into the transaction table and then use it on your receipt
page and in your emails etc.
