The original query is fine, and has the boost as expected:
((+language:eng +(
CutoffQueryWrapper((+value_0:bunker~0.8332333 +value_0:hill)^0.6666667)
CutoffQueryWrapper((+othervalue_0:bunker~0.8332333
+value_0:hill)^0.5714286)
CutoffQueryWrapper((+value_0:bunker~0.8332333
+othervalue_0:hill)^0.5714286)
CutoffQueryWrapper((+value_1:bunker~0.8332333 +value_0:hill)^0.6666667)
CutoffQueryWrapper((+othervalue_1:bunker~0.8332333
+value_0:hill)^0.5714286)
CutoffQueryWrapper((+value_1:bunker~0.8332333 +othervalue_0:hill)^0.5714286)
...
CutoffQueryWrapper((+othervalue_7:bunker~0.8332333
+value_7:hillmonument~0.8332333)^0.85714287)
CutoffQueryWrapper((+value_7:bunker~0.8332333
+othervalue_7:hillmonument~0.8332333)^0.85714287)))^3.0)
(
CutoffQueryWrapper((+value_0:bunker~0.8332333 +value_0:hill)^0.6666667)
CutoffQueryWrapper((+othervalue_0:bunker~0.8332333
+value_0:hill)^0.5714286)
CutoffQueryWrapper((+value_0:bunker~0.8332333
+othervalue_0:hill)^0.5714286)
CutoffQueryWrapper((+value_1:bunker~0.8332333 +value_0:hill)^0.6666667)
...
))
The rewritten query is odd. Here's a sample:
((+language:eng +(
CutoffQueryWrapper((+() +value_0:hill)^0.6666667)
CutoffQueryWrapper((+() +value_0:hill)^0.5714286)
CutoffQueryWrapper((+() +othervalue_0:hill)^0.5714286)
CutoffQueryWrapper((+() +value_0:hill)^0.6666667)
CutoffQueryWrapper((+() +value_0:hill)^0.5714286)
CutoffQueryWrapper((+() +othervalue_0:hill)^0.5714286)
CutoffQueryWrapper((+(value_2:bunker value_2:burker^5.997396E-4)
+value_0:hill)^0.6666667)
CutoffQueryWrapper((+() +value_0:hill)^0.5714286)
...
CutoffQueryWrapper((+() +(()^0.5555556))^0.85714287)))^3.0)
(
CutoffQueryWrapper((+() +value_0:hill)^0.6666667)
CutoffQueryWrapper((+() +value_0:hill)^0.5714286)
CutoffQueryWrapper((+() +othervalue_0:hill)^0.5714286)
CutoffQueryWrapper((+() +value_0:hill)^0.6666667)
CutoffQueryWrapper((+() +value_0:hill)^0.5714286)
CutoffQueryWrapper((+() +othervalue_0:hill)^0.5714286)
CutoffQueryWrapper((+(value_2:bunker value_2:burker^5.997396E-4)
+value_0:hill)^0.6666667)
CutoffQueryWrapper((+() +value_0:hill)^0.5714286)
...
CutoffQueryWrapper((+() +(()^0.5555556))^0.85714287)
CutoffQueryWrapper(+() +(()^0.6666667))
CutoffQueryWrapper((+() +(()^0.6666667))^0.85714287)
CutoffQueryWrapper((+() +(()^0.5555556))^0.85714287)
)
As you can see, there are a lot of repeats, a lot of blank matches, but the
original boost *is* still there. I really can't interpret this any further -
the many blank and repeated matches seem wrong to me, but the scorer
explanation seems even more wrong. Any ideas?

I see a lot of unexpected zeros - queryNorm has factors if idf and the
boost in it - the fact that it's 0 suggests that you used a 0 boost.
Why don't you do a toString() on your query and see if it's what you expect.
