the backreference needs a double backslash, and then there's no confusion.

ereg("fla(r[gpm]) wobba1", $foo)
Note the ``1'' -- is that an octal 1 in my charset, or a backreference?
The backslash-x-number notation is great for hexidecimal, but the backslash-number
notation conflicts with the notation for backreferences (in ereg(), e.g.)
Are there backreferences? The manual refers us to the regex(7) manpage, which does
describe them.
Even if there's not, I recommend backslash-zero-octal, as historically, octals are
represented with preceding zeros. Backreferences are positive integers (which mortals
usually describe with no leading zero), so there's no conflict.
