I clicked at recompile all by mistake, now I have to re-start my mod from the beginning? Can I still clean the mod and correct these two script errors?
You should use recompile all only with Wrye's vaccine or both Tribunal.esm and Bloodmoon.esm loaded.
Like with GMSTs, there are different ways to clean dirty scripts.
The first-to-know-for-a-modder way , requiring no external tools, is using TESCS detail view.
Make a backup copy of your mod (always a good thing to do before changing things)
Click FIle\Data Files..., select your mod and set it as active. Now click Details... button to open details panel.
Sort items by type clicking the ID column header, look for SCPT entries, highlight any of the DagothUrCreature1, EndGame, Float, LorkhanHeart, SignRotate scripts (you can use standard Windows ctrl + click and shift + click for multiple selection).
Press Delete on keyboard to mark them as to be ignored, confirm ( there should be I markers in the Ignored column now)
Click Close button to close details panel, now you can load your mod ignoring those scripts clicking OK button in the Data Files panel.
Save your just loaded/cleaned mod to make changes effective, reload it and it should be ok.
This procedure will be often of use when you want to remove undesired things from your mod.
Or you could use a external tool: simpler to use is TESTool:
Clean ESP/ESM file, in the Options panel uncheck everything except "Don't change plugin filename" , "Retain file name when cleaning".
If you don't know how dialog and cell cleaning work, check also "Restricted dialog cleaning", "Restricted cell cleaning".
Click done, click Execute
You could use also Enchanted Editor, TESame, probably also TES conflict detector but first 2 options are the best IMO.
[EDIT]added backup hint, typo fixes
