There _is_ no advantage to full Condorcet in primary elections. The trivial example, with only two candidates for a given party, is actually a common one:
(loosely taken from 2002 California gubernatorial race:
Republicans: 30 Simon 25 Riordan
Democrats: 45 Davis
Your proposal would elect conservative Simon in the Republican primary (the same as plurality), even though polls showed that centrist Riordan was the only Republican likely to defeat Davis in the general election.
If you don't like the CA 2002 example, try Louisiana 2000 [(Duke vs Roemer) vs Edwards] or CA 2003 [(McClintock vs Schwarzeneggar) vs Davis].
In all these examples, the Condorcet candidate in the Republican primary is a sure loser in the general election. Looking forward, the Demos seem to be splitting into progressive and centrist factions.
