The order of skills depends on the initial map seed (which is generated when the new game is started) and pre-defined for a given hero. See this method for details and comments:

fheroes2/src/fheroes2/heroes/heroes.cpp

Lines 2170 to 2201 in 4fd43fb

Heroes::HeroSeedsForLevelUp Heroes::GetSeedsForLevelUp() const
{
/* We generate seeds based on the hero and global world map seed
* The idea is that, we want the skill selection to be randomized at each map restart,
* but deterministic for a given hero.
* We also want the available skills to change depending on current skills/stats of the hero,
* to avoid giving out the same skills/stats at each level up. We can't use the level field for this, as it
* doesn't change when we level up several levels at once.
* We also need to generate different seeds for each possible call to the random number generator,
* in order to avoid always drawing the same random number at level-up: otherwise this
* would mean that for all possible games, the 2nd secondary
* skill would always be the same once the 1st one is selected.

Yes, I see. The only way to change upcomming choice is to upgrade hero skills without raising experience. It's a pitty that choice doesn't necessarily include one skill that was already selected before.
