Not sure why did you bother putting the bounty up, coding it yourself wouldn't be quicker ?
Good question - for myself I am extremely busy with the CIYAM project (AT is only actually a side-project for me) so I don't have time to work on creating AT for a Bitcoin clone at the moment.
If I do find myself with the free time then I will have a go at creating the Script version of AT myself (so the bounty was put up to encourage others that might have the time to do this before I do).
I think that Vasilis doesn't know the Bitcoin code very well (he is a Java coder) so his reason for not doing this would be most likely because of that.
