Kind of. The load order is dependent on the time/date of modification of the file.
If several mods all have the same time/date, then load order can be a bit iffy.
Far better to fix it.
Two ways: Simply run BOSS (after turning off Lock times - Right click the "file" header in the mods tab of Wrye Bash to see if it is turned on).
Or, Select all your mods in Wrye Bash, right-click, go to File -> redate. Give it a starting date (a year or so ago is good) and then it will redate all your mods according to their current load order.
