Mappings for tab navigation don't work

[Mr.SpOOn]

Hi,
in my .vimrc I have this:

map <silent><A-t> :tabnew<CR>
map <silent><A-Right> :tabn<CR>
map <silent><A-Left> :tabp<CR>

So I should open a tab just pressing Alt + t, and moving with alt left
or right arrow. This just doesn't work and when I press them nothing
happens.

I searched in the .vimrc and it seems that this is the only mapping
for that keys. Why they don't work? What else can I check?
I'm running vim 7.2, inside screen.

Thanks.

The <A-t> one is not going to work, since it corresponds to "ô" (try
inserting a ô in normal mode), but do the <A-Right> and <A-Left>
mappings really not work? They do work for me.

Also, please note that your mappings would work only in normal mode.
For mor info, see
:help map

I am in Italy and on my keyboard there isn't such a character.

Yes, I do know they only work in normal mode. It is really strange.
