"Blind" refers to the fact that the command never appears on the
CMline. There isn't (or shouldn't be) any difference in the way the
command itself operates. (Not sure what you mean by "doesn't look at
what it's doing.")

If the problem were processing speed, then BC sortXC shouldn't work
either, no?

You mean like this: TF BX ci /"//Q2 >TF DF BF DF BX sortQ2 TF 

You'd think it would make a difference. But it doesn't.

Here's the fix: Transfer the cursor from the text area to the CMline
after DeFining the list and before SORTing. In other words, insert a
func GH immediately before BX sortQ2 . In PSEUDO code:

TF BX ci /"//Q2 TF DF BF DF GH BX sortQ2 TF 

In executable XPL (DECODE first, of course):

XPLeNCODE v2.0
b-gin [UNTITLED]
[TF_][BX_]ci /"//[Q2_][TF_][DF_][BF_][DF_][GH_][BX_]sort[Q2_]
[TF_]{<}EX{>}[cr|lf][cr|lf]
-nd
XPLeNCODE

Works here.
