Radiscreen can RANK.

Oops! The post you link from tetranomad back in 2012 was replying to my post back in 2012 in which
I stated 'I don't know how to approach rank-order of the results of a custom factor made up from an equation of factors.
Keelix did once mention that he had implemented a PERCENTRANK function.'

But as tetranomad noted:
' I think a Radiscript formulation of this screen is perfectly do-able, the questions are whether it would be parsed by RunRadis'
And although the Rank function runs in the Excel macro version which tetranomad pointed out to me more than 10 years ago
(I'm a slow learner or getting a little senile). However it doesn't work in Runradis at least for the Ocaml version.

C:\runradis>pick rankPefDvMo2018 -max 10
Fatal error: exception Lexer.Syntax_error("rankPefDvMo2018.txt:8: 'RANK' not a keyword")

No standard SIP screens currently use the rank function. An typical output from a screening using runradis.
C:\runradis>pick yldearnyear -max 10
