priomap unclear

Hello there!
I was trying to figure out what is this 'priomap' is all about and found
some ambiguity in what I've found.

There is this well-known table:

> TOS Bits Means Linux Priority Band
> ------------------------------------------------------------
> 0x0 0 Normal Service 0 Best Effort 1
> 0x2 1 Minimize Monetary Cost 1 Filler 2
> 0x4 2 Maximize Reliability 0 Best Effort 1
> 0x6 3 mmc+mr 0 Best Effort 1
> 0x8 4 Maximize Throughput 2 Bulk 2
> 0xa 5 mmc+mt 2 Bulk 2
> 0xc 6 mr+mt 2 Bulk 2
> 0xe 7 mmc+mr+mt 2 Bulk 2
> 0x10 8 Minimize Delay 6 Interactive 0
> 0x12 9 mmc+md 6 Interactive 0
> 0x14 10 mr+md 6 Interactive 0
> 0x16 11 mmc+mr+md 6 Interactive 0
> 0x18 12 mt+md 4 Int. Bulk 1
> 0x1a 13 mmc+mt+md 4 Int. Bulk 1
> 0x1c 14 mr+mt+md 4 Int. Bulk 1
> 0x1e 15 mmc+mr+mt+md 4 Int. Bulk 1

and also well-known explanation to it:

>"[...]

So looking at the table, there we can find out that matching "band" to
TOS field value "Bits" gives us something quite different from what this
"priomap":

Priomap is:
1, 2, 2, 2, 1, 2, 0, 0, 1, 1, 1, 1, 1, 1, 1, 1

while table shows:

band: |1 |2 |1 |1 |2 |2 |2 |2 |0 |0 |0 |0 |1 |1 |1 |1 |
------+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
bits: |0 |1 |2 |3 |4 |5 |6 |7 |8 |9 |10|11|12|13|14|15|

Quite different, huh?
priomap: 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
table: 1 2 1 1 2 2 2 2 0 0 0 0 1 1 1 1


So how is that table and priomap connected? What do those "priomap"
numbers means?
