It should "work perfectly" as is in a syntax file, too. I suspect that
you have some syntax priority issues going on.

* later syntax takes priority over earlier syntax:
syn clear
syn match One 'abc'
syn match Two 'abc'

hi link One Function
hi link Two Identifier

use this with a file containing only "abc". Result: abc is highlighted
using #2 (Identifier). Swap syn-matches One and Two and abc will be
highlighted using #1.

* regions have their own syntax highlighting, and may contain other
syntax recognition.
* nextgroup elevates priority of such syntax

Anyway, its involved. So, may I suggest trying my plugin

http://www.drchip.org/astronaut/vim/index.html#HILINKS

with its :HLT! command, move the cursor over the url: you'll be told
what highlighting groups are in use with the text under the cursor.
