You forgot point zero in your coordinates table -- NEVER forget zero =)
Otherwise, good code =) Try this:

obj_test_cube_xy_coords:
 dc.b 00,00,0    ;accounts for point zero
 dc.b 96,34,0    ;point one
 dc.b 64,34,0    ;point two
 dc.b 69,39,0    ;etc.
 dc.b 91,39,0
 dc.b 96,66,0
 dc.b 64,66,0
 dc.b 69,61,0
 dc.b 91,61,0
