You mean the hash keys?

Code:
perl -le'
      
 %h = (  
    C1 => { x => 41.9 , y => 5.79999999999995},
    "c2 288" => { x => 428.05 , y => 5.79999999999995},
    turn => { x => 493.25 , y => 209.85},
    "0001" => { x => 530.1 , y => 195.7},
    "000001" => { x => 235.25 , y => 728.15},
    XYZ => { x => 56.65 , y => 716.7},
    AS => { x => 78.7 , y => 716.7},
    HOUSE => { x => 56.65 , y => 708.3},
    dsf => { x => 89.75 , y => 708.3},
    YIPPE => { x => 106.3 , y => 708.3},
    DAY => { x => 150.45 , y => 708.3},
    12 => { x => 56.65 , y => 699.9},
    INGG => { x => 95.25 , y => 699.9},
    CORNER => { x => 122.85 , y => 699.9},
    "Light 049319" => { x => 56.65 , y => 691.6},
    "(023117)" => { x => 164.8 , y => 678.35},
    "01201" => { x => 57.5 , y => 5.79999999999995},
    );
    
    print join $/,
        sort {
            $h{$a}{x} <=> $h{$b}{x} ||
            $h{$a}{y} <=> $h{$b}{y}
                } keys %h;
    '

NAME

       mlib_ImageColorXYZ2RGB - XYZ to RGB color conversion

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_ImageColorXYZ2RGB(mlib_image *dst, const mlib_image *src);

DESCRIPTION

       The mlib_ImageColorXYZ2RGB() function performs a color space conversion from CIE XYZ to ITU-R Rec.708 RGB with D64 white point.

       The source and destination images must be three-channel images.

       It uses the following equation:

	 |R|   |cmat[0] cmat[1] cmat[2]|   |X|
	 |G| = |cmat[3] cmat[4] cmat[5]| * |Y|
	 |B|   |cmat[6] cmat[7] cmat[8]|   |Z|

       where

	 cmat[] = { 3.240479, -1.537150, -0.498535,
		   -0.969256,  1.875992,  0.041566,
		    0.055648, -0.204043,  1.057311 };
	 src[x][y] = { X, Y, Z };
	 dst[x][y] = { R, G, B };

PARAMETERS

       The function takes the following arguments:

       dst    Pointer to destination image.

       src    Pointer to source image.

RETURN VALUES

       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
