That's very curious. The Gurre-Lieder vocal score (for the entire work) was issued in 1912 or 1920 as I recall, so it would be free in the USA and the 50 pma countries by now. The six-year delay could have been due to extended correspondence between Helene Berg and the copyright office - she may have actually applied for renewal in 1955 - or possibly the result of a presidential proclamation allowing an extended renewal period for citizens of Austria since they were unable to conduct business with the copyright office during WW II. What was different about the excerpts that warranted a separate copyright claim, etc.? It's very odd in any case.
I will double check on the Lulu score. If there was no renewal, it is very possibly free in the USA. However, you also have to check the copyright office online database to see if they filed an NIE back in 1996-98 - possibly anytime up through the end of 2005. Berg was still under copyright in Austria when GATT/TRIPS came into effect (1996), so it would have been eligible.
