First off, vim regular expressions (by default, anyway), require you to
use a \ with () and {N}. That, in itself, prevents \1 from working here
- there simply is no match for the literal string '(P[0-9]{2}'.
Secondly, I'd use single quotes to avoid having to quote the
backslashes.
With another tweak for numbers, I'd go for eg. (untested, though)
let s:line1 = getline(1)
if s:line1 =~ '^\(P\d\{2\}\) \1\.\d'
setf sierrasym
endif
