I think the script below will do what you want. Just copy it to your script window, select all lines and execute by pressing Enter. A column will be created for the integral curve.

integrate col(2); // integrate column 2
# integral values go to the hidden dataset _integ_area, final area to integ.area
wo -a 1; // add a column
col(3)=_integ_area; // save integral curve to column 3
get col(3) -e npt; // how many points in integral?
loop (i,1,npt) {
# find 10% point
if(col(3)[i]>integ.area/10) break;
};
type "area: $(integ.area)";
type "10% point: $(i)";
type "X[$(i)]: $(col(1)[i])";
del -as; // delete _integ_area dataset
