So Eric, you're handing this arg as per documentation (info)
* :hlines: `no' (default)
  Strips horizontal lines from the input table.

But you've missed handling this arg:
* :colnames `nil' (default) 
  If an input table looks like it has column names (because
  its second row is an hline), then the column names will be removed
  from the table before processing

I think that org-babel-ref-index-list should receive the stripped table,
i.e. these elements should have been removed:
  ("search" "replace") hline

I think the fix is somewhere in org-babel-disassemble-tables, 
not in functions it calls (downstream from it). 
But in my debugging it always returned (nil nil nil)?
