I didn't test them, but these changes could help:

1. Change the order of `--citeproc` and `--lua-filter=...` on the
   command line. The order in which these are given is also the order
   in which they are applied. We want the Lua filter to be applied
   first.

2. Make sure that the `references` field is populated by filtering the
   Pandoc element and adding
   `doc.meta.references = pandoc.utils.references(doc)`

Here's the updated filter:

``` lua
function Pandoc (doc)
  local meta = doc.meta
  meta.references = pandoc.utils.references(doc)
  meta.bibliography = nil -- prevent citeproc from parsing this again

  for _, ref in ipairs (meta.references or {}) do
    ref.title = ref.title:walk {
      Str = function (str)
        return str:gsub(':$', ',')
      end
    }
  end

  return pandoc.Pandoc(doc.blocks, meta)
end
```
