Uh, no. It doesn't have to be a contest of arms. If anything, using such an opportunity makes him even more qualified. If he fought Darth Plagueis, there's a chance he'd be killed (or badly wounded), which is hardly useful if he planned on becoming the next Dark Lord.
Malak chose to eliminate his master in a similar way, firing on his command ship when it had been crippled and boarded by Jedi strike teams.
Part of being a Sith is about cunning, and making use of such opportunities.
