This is because the CellStyle of a Cell is not an Option, but rather,
it is an argument.  Here are two ways to do what you want to do.
Assume that you have the cell selected in the notebook nb (and that it
is editable) and the the new styls is a String called newstyle

SelectionMove[nb, All, Cell]

cell = NotebookRead[nb]

cell = cell /. Cell[x_, style_, y___] :> Cell[x, newstyle, y];

NotebookWrite[nb, cell]

Here is another approach using FronEnd functions

SelectionMove[nb, All, Cell]

FrontEndExecute[{FrontEnd`FrontEndToken[nb, "Style", newstyle]}]
