Good call on the rocking of the carboy. A friend told me rock the carboy slowly in an effort to submerge the fruit again but it just didn't sound right.
The fruit was pulverised as it was being poked through a funnel while dropping into the beer, so yeah, somewhat "crushed" but not completely.
I'm keeping an eye on it. The fruit in my sour cherry chocolate stout and chardonnay has risen to the top, just not far ~above~ the top level. Hopefully the grapes will fall back in as you mentioned.
