Bukkit

I run the script <relativeloc:<playerloc>:1,1,1> and returns x,y,z,0,0 not x,y,z..It is a bug?

No, This is not a bug, just a feature that doesn't work in a lot of cases. This is the way Lexlaiden designed it to work. However, <playerloc> returns a single string of pure integer map block coordinates. <relativeloc::> attempts to create a full player Position with direction and visual arguments. These are two different things. These two cannot be used in tandem as the documentation suggests and expect usable results. If you want a way to fix the string for just x,y,z coords from what <relativeloc::> produces, see my script on fixing this in the Share Your Scripts subForum.
