Allowance would have to be made for the up to 60,000 syrian troops that are reported to have joined the FSA.
Though numerically and equipment wise the syrians would appear to have a distinct advantage over Jordan. Jordan would fight with a secure rear while syria would be fighting with an unknow number of insurgents opperating behind it.
It might be a battle Syria can win but it is not one in the current situation that it can afford to fight, pulling the army out of the cities to confront Jordan would mean giving up most of the country to the FSA.
