This should work in the next version; it's been fixed for quite some time now. Here's what I get in the development build:
In[1]:= Integrate[Cos[a*x]*CosIntegral[b*x], {x, 0, Infinity}, Assumptions -> a>b>0] //InputForm
Out[1]//InputForm= -Pi/(2*a)
In[2]:= Integrate[Cos[a*x]*CosIntegral[b*x], {x, 0, Infinity}, Assumptions -> b>a>0] //InputForm
Out[2]//InputForm= 0
In[3]:= Integrate[Cos[a*x]*CosIntegral[b*x], {x, 0, Infinity}, Assumptions -> a==b] //InputForm
Out[3]//InputForm=
If[b >= 0, -Pi/(4*b), Integrate[Cos[b*x]*CosIntegral[b*x], {x, 0, Infinity},
Assumptions -> b < 0 && a == b]]
Sorry for the inconvenience.
