Have you checked the definition of these functions, like SUM(), in the OpenFormula specification
before you get too carried away?  Those have to be reconciled with the data type that a cell
is identified as carrying.  So if the cell is identified as carrying Text, rather than Number,
the rules of OpenFormula prevail.  Now, OpenFormula does not dictate how the type of a cell
is established and how entries via the UI are converted, so you have some leeway there.  Just
be careful, please.

Also, it is preferable, when comparing what is correct or not in interchange among implementations,
to compare with the way the same ODS file (not XLS) is processed when opened by Excel 2013,
for example.  If there is still an interoperability discrepancy, we can narrow that down.
 (Conversions among ODS and XSL[X] just create even more places for possible round-trip defects
having nothing to do with the rules for the SUM function itself.)

Finally, is there a bug report on this, with an example of what is claimed to be a defective
computation?.  It would be good to ground this situation with some actual spreadsheet files
that we can all inspect and be clear about what we are looking at.

I have been working in IT for 32 years, from Mainframe design through to cloud integrations
within VM ESX servers I build. So I know a little bit about hardware and software. I found
the issue, and a team of developers I know have found a resolution.
The backend code for the function doesn't equate for single routines of sum in other formats
based on the cell, that why it errors. However they have proposed a code change that sums
any value numeric where the format is not equal to an integer.
The code allows and can distingish the Value enetered, irraspective of format, and provides
the total. At the moment OpenOffice doesn't, its flawed.
