Plink 1.9 equivalent of --score sum in Plink 2.0 I have previously performing Allelic scoring in Plink 1.9 using: 

plink \ 
--score sum sumstats.txt\


However, it seems this has changed in Plink 2.0. What is the equivalent function for Allelic scoring?
plink2 --score cols=+scoresums


See https://www.cog-genomics.org/plink/2.0/general_usage#colset and https://www.cog-genomics.org/plink/2.0/score for details.
