Keyword order appears to matter for the \blank command. The following
example shows all orderings for the set {dimension, nowhite, samepage},
some of which work and some of which do not. It also shows two orderings
of {dimension, nowhite, samepage, disable}; one works and the other does
not. This happens with TL13 as well as the 2014-06-01 beta.
I can find no discussion of keyword ordering in the wiki, on the mailing
list, or in the manuals.
Is this intentional, and if so, with what other commands are keywords
similarly constrained? Whether or not this is intentional, can a
developer please provide a suggested ordering to use until this is
better documented or corrected? The order that keywords are presented in
the wiki and in the reference manual are among those that fail.
\starttext
\subject{Without disable}
12pt,samepage,nowhite\blank[12pt,samepage,nowhite]
works
12pt,nowhite,samepage\blank[12pt,nowhite,samepage]
fails
samepage,12pt,nowhite\blank[samepage,12pt,nowhite]
fails
samepage,nowhite,12pt\blank[samepage,nowhite,12pt]
works
nowhite,12pt,samepage\blank[nowhite,12pt,samepage]
works
nowhite,samepage,12pt\blank[nowhite,samepage,12pt]
works
\subject{With disable}
12pt,samepage,nowhite,disable\blank[12pt,samepage,nowhite,disable]
works
samepage,12pt,nowhite,disable\blank[samepage,12pt,nowhite,disable]
fails
\stoptext

The command
\enabletrackers[vspacing.spacing]
Gives some insight in the processing order. Samepage is an option that
changes the order (gravity) so it triggers a flush.
At some point I will redo part of that code (as it was written very
early in the mkiv/luatex development) but not today.
