D3js palettes not being implemented in schemes correctly

tw  lowess mpg weight ||                                                    ///

    3 "2" 4 "3"                   ///

    scheme(d3test) 

Graph doesn't implement the palette colors correctly. Lines 300 - 310 of the resulting scheme file read:

color p       gs6
color p1 "127 127 127"
color p2 "140 86 75"
color p3 "148 103 189"
color p4 "188 189 34"
color p5 "214 39 40"
color p6 "227 119 194"
color p7 "23 190 207"
color p8 "255 127 14"
color p9 "31 119 180"
color p10 "44 160 44"

The colors are being interpreted and written to the scheme file is a bizarre order that doesn't match the ordering in the extras dataset:

colorid      pcolor      rgb                maxcolors        seqid                  meta
