Nick and Chris,
There is no way to control the order of overlapping spatial objects in either MapInfo Pro or Spectrum Spatial (the Analyst application is not even part of the issue) without a query. Spatial index storage does not have this capability.
However, in MapInfo Pro, when you edit geometries, the results are stored temporarily in a transaction file. This allows you to revert your changes and forces you to commit them if that is what you want.
While that transaction file is in use in MapInfo Pro, the edited geometries will be rendered last, I believe, giving you the visual impression that they are now on top. But this is only temporary. Once the table is saved, the spatial index will be reintegrated and the order will then become non-deterministic of any attributes once again.
However, if you create a query table in Spatial Manager and make sure your layer is pointing to it, that query will be applied and that will affect the order of what is returned and what is drawn on the map. Depending on the query, of course, performance can also be affected. I would suggest indexing the column or columns involved in the query.

Chris,
Can you check the polygon order in the original MapInfo table in Pro. If it is the same as displayed in SS you could try editing the required polygon slightly (e.g. add node and then remove node) and that 'should' move that polygon to the top.
I haven't tried this though and I'm not 100% sure the polygon order is the same in SS as it is in Pro,
HTH

I have a tab file layer displayed in SSA where some of the polygons are overlapping. So in some places clicking on the map brings back just one result but in others three might be returned. Where there are multiple results there doesn't seem to be any logical order to the way the data is displayed in the information pane eg it's not alphabetical. Is there a way to set the order that results are displayed here? I have had a request to show a particular school catchment area at the top of the list when there are multiple results but can't find a way to do this.
