No, they are not.

They are not "missing". They are not supposed to be there.

They have not been delayed.
Philippe, if you would refer to the 10646 Amendments 2 and 3
*first*, before going on about this, you would sow less confusion.
The contents of Amendment 3 is *NOT* part of Unicode 5.0,
except for 4 Devanagari characters for Sindhi accelerated
into Unicode 5.0.
Amendment 3 is still at its PDAM stage, and has two more
ballots to go, so it would be inappropriate to be including
Lepcha, Ol Chiki, Vai, and Saurashtra into Unicode 5.0 --
they are subject to further review and updates before they
are finished. Furthermore, it is rather likely that at the
WG2 meeting two weeks from now, more characters, or possibly
even entire scripts may be added to Amendment 3.

There has been no "big reduction". Those characters are either
in Amendment 3 or have yet to be added to *any* amendment for
10646 yet.
When using the Pipeline summary on the Unicode website it is
vital that you pay attention to the ISO Status field. If a
character or script is not marked there as being in ISO Status
"Stage 6" then it isn't in Amendment 2, and (with the exception
of the 4 Devanagari additions for Sindhi) won't be going into
Unicode 5.0.

As intended.

Phags-pa is not laid out horizontally.

Tibetan is laid out horizontally, not vertically.

No.

As above. It isn't in Unicode 5.0.

No there isn't.

No comment.
