I ended up writing a function:

    def onchange_supplier_invoice(self, cr, uid, ids, reference, context=None):

        msg = reference + 'has already been used!' 
        res = {'reference': reference, }

        if not reference:
            return res

        # Get all Supplier Invoices
        invoice_ids = self.search(cr, uid, [('type','=','in_invoice')], context)

        # Get all the references for all Supplier Invoices
        invoices = self.read(cr, uid, invoice_ids, fields=['reference'],context=context)

        # Check for duplicates
        for inv in invoices:
            if inv['reference'] == reference:
                raise osv.except_osv('Possible duplicate Invoice!',msg)

        return res

And triggering the function via on_change in the relevant field (in this case reference).

<field name="reference" string="Invoice Number"

Depending on the use case, searching for Supplier Invoices matching the current supplier (if populated) may be better.
