You'd use a Scoped attribute definition that slaps on %{idp.scope} to
your sAMAccoutName attribute.
Then an Encoder to send it as mail attribute with a relyingParties
XML-attribute enumerating the SPs that require this hack.

No scripting necessary and likely will fix your issue of duplicate
values, too.
