Nothing wrong with the expression; the interpreter has a bug.
I guess few people use verbal agenda to construct trains, so this hasn't
been caught before. Most often agenda is used to select a single verb
from the agenda, so agenda expects the verb to return a scalar.
I tried a workaround. I boxed the list so that the verb returns a scalar,
which should have no effect on the train produced (the box would
theoretically just put a pair of parens around the train):
(-`%)@.((<0 1)"_) 1 2 3 4 5
|length error
| (-`%)@.((<0 1)"_)1 2 3 4 5
but no joy.

Added parens to make the rank apply to the entire expression.
((-`%)@.((0 1))"_) 1 2 3 4 5
0 1.5 2.66667 3.75 4.8
Is this what you wanted?
