Im sorry im not best scripter in UO, but as i understand EVAL RAND(500) is random number between 0 and 500 second i dont really know how SRC.SKILL return value 50.5% skill its 505 or 50.5.
And you should start from easiest function. With 50% of skill if its 50.0. The chance to get last ELSEIF is about 1:30000. You really want this ?
If you could declare random value in the beginning of the script. etc
x = EVAL RAND(500) + SKILL if player have 50% skill and he rolls 100, x would be 150 then declaring chances

if X >= 550 then
function1 (rarest)
elseif x >= 400 then
function2
elseif x >= 300 then
function3
elseif x < 300 then
function4

function1 gona happen 1:500 times with 50% skill and 50:500 with 100% skill
function 2 gona happen 150:500 times with 50% skill and 200:500 with 100% skill
function 3 gona happen 250:500 times with 50% skill and 300:500 with 100% skill
and function4 gona happen 350:500 times with 50% skill and 400:500 with 100% skill
