A functional central limit theorem is established for weighted occupancy processes of the Karlin model. The weighted occupancy processes take the form of, with $D_{ n,j}$ denoting the number of urns with $j$-balls after the first $n$ samplings, $\sum_{ j=1}^na_jD_{ n,j}$ for a prescribed sequence of real numbers $(a_j)_{ j\in\mathbb N}$. The main applications are limit theorems for random permutations induced by Chinese restaurant processes with $(\alpha,\theta)$-seating with $\alpha\in(0,1), \theta>-\alpha$. An example is briefly mentioned here, and full details are provided in an accompanying paper.
