Howsagoin,

:  minimize(+Goal, ?Template, +Lower +Upper, +Percentage)
[snip]

The problem is that Percentage has to be an integer.
Therefore, your proposed solution cannot be used for
all combinations of Lower and Upper.

Also I just realised that I cannot use Mark's suggestion
  bb_min( labeling( LIS ), EXPR, bb_options with [delta:N] )
because this may rule out solutions between whose costs are
between the cost, COST, of the last found solution and
COST + N - 1.

Thanks anyway.
