Every numeric priority scoring system I've ever worked with at every company I've ever worked with has devolved into this: Start with P1 (high), P2 (medium), and P3 (low). Sooner or later, an exec will swoop in and declare something Even Higher Priority Than P1!!! So, "P0" gets invented, and after some time, you have tons of P0 issues, meaning P1 is the new "medium", P2 is the new "low" and P3 becomes "never". Then something comes in that is Even Higher Priority than P0!!! And now, you're stuck.
For this reason, I always advocate reversing the numbers. The higher the P number, the higher the priority. So you never run out of numbers to express how much more urgent and earth shattering your next bug is. Try it!
