Very simply, since a yellow stat (glorious) gives something like 116 dex/290 patt... patt>dex. (when choosing between, say, stam/dex, and stam/patt).
so order for scouts would be patt>dex>stam.
However since scouts give 1 patt per str and 1 patt per dex, you could choose str/patt over dex/patt, if the str/patt is from a higher instance than dex/patt (haven't made calculations with scout dex passive though).
a good way to stat could be:
dex/patt x 2 (glorious, hero)
str/patt x 1 (glorious)
stam/patt x 2 (hero)
patt/hp (hero)
depending on how much survivability, you can remove patt/hp, and put in another str/patt from hero, or cheaper, use dex/patt crimson.
Since str and dex give little patt, i've also seen scouts going something like:
stam/patt x 3 (glorious, hero, crimson)
patt/hp x 1 (hero)
dex/patt x 2 (glorious, hero)
since losing 2 dex ( or str) per piece, is like losing 278 patt per piece of gear, x15 pieces of gear -> 4176, you sacrifice 4176 patt (when unbuffed) and gain like 20k hp... o.O )
But honestly i think you're not at this stage of the game yet.
